"One of the construction blocks from which the pier was fashioned weighs an estimated 440 tons (equal to nearly 600 full-size cars) and several other blocks are between 100 and 150 tons. The quarry for these giant blocks was on the western shore of Titicaca, some ten miles away. There is no known technology in the ancient Andean world that could have transported stones of such massive weight and size. The Andean people of 500 AD, with their simple reed boats, could certainly not have moved them. Even today, with modern advances in engineering and mathematics, we could not fashion such a structure." source: sacredsites .com
The 440 ton estimate has been disputed. The largest stone at Tiahuanaco is probably about 130 tons. The larger estimate seems to have been the result of a misrepresentation that has been repeated without scrutiny by many sources. A similar incident seems to have happened in the case of the Baalbek stones that have been estimated at over 1,000 tons. The more reliable estimate for the trilithon stones is probably 700 to 900 tons. The most reliable source for these estimates is the stone themselves. If it turns out they are larger the bigger estimates can be restored.
Tiahuanaco is approximately 12,500 ft. above sea level. the air is much thinner than at sea level. Farming is much tougher and people who are not accustomed to the altitude tire easy from lack of oxygen. Even people who are accustomed to the altitude would still have a hard time coping with the environment let alone moving stones over 100 tons over rough terrain.

Ollantaytambo is 9,000 ft. above sea level and it appears to have 6 colossal stones well over 100 tons although I don't have exact dimensions.

Some believe the walls were a form of fortification. Like much Inca stonework there is still mystery surrounding how they were constructed. The structure is built in such a way that a single piece of paper will not fit between many of the stones. This precision, combined with the rounded corners of the limestone blocks, the variety of their interlocking shapes, and the way the walls lean inward, is thought to have helped the ruins survive devastating earthquakes in Cuzco. The longest of three walls is about 400 meters. They are about 6 meters tall. Estimated volume of stone is over 6,000 cubic meters. The largest limestone block is estimated at 128 tonnes. source: "Seventy Wonders of the Ancient World" edited by Chris Scarre 1999

These include lines which ran absolutely true for 6 miles or more.

It is difficult to imagine how the islanders moved such a large statue from the quarry four miles (six kilometers) away; Paro is the island's largest transported moai. Lying face down, toppled from its ahu, Paro weighs 82 tons and is 32.45 feet (9.89 meters) long.
Easter Island is only 64 square miles. It has a very limited amount of fresh water. There is a small lake in the top of the dormant volcano however when rainfall is low that probably doesn't provide as much water. It would be helpful to know what the climate was like while the people that lived there were moving those stones. It is hard to imagine primitive people having much spare time in such a remote area. simply growing food or fishing should take up a lot of their time.

The Olmecs carved about 300 colossal monuments including a lot of Heads and Alters weighing between 5 and over 50 tons. They transported them between 35 and 65 miles through the rain forests. The biggest Olmec cities were at San Lorenzo, Tres Zapotes and La Venta. source: "Seventy Wonders of the Ancient World" edited by Chris Scarre 1999
The colossal heads are made out of volcanic basalt which only weighs about 1.9 tons per cubic meter. The Rancho Cobata is approximately 24 cubic meters probably weighs about 45 tons. This may mean that The Seventy Wonders of the Ancient World may have over estimated the largest stone but not by much. There are few stones with this low a density.

"The Maya somehow transported enormous stones through the jungle from distant quarries, apparently without the aid of either wheeled carts or beasts of burden. Artists then used only rudimentary stone tools to execute the intricate carvings, before raising the ponderous sculptures to their present vertical positions. Stele E at Quirigua weighs an astonishing 65 tons and stretches 10.5 meters in length, with sculptures covering its 8-meter panels." source: mayadiscovery.com
Stele D, Alter M and Zoomoorph B shown in the wikipedia or delange.org site all appear to be at least 15 to 30 tons.

In addition to the pyramids of the sun and the moon there are about 600 pyramid like structures most of which have 3-5 levels and a flat platform. there are also many apartments found in the city. the original city was supposed to cover about 8 square miles. It was said by the Aztecs to have been surmounted by a huge stone figure related to the moon but this figure was uncovered (weighing 22 tonnes and was somehow lifted to the top of the pyramid) and it is thought more likely that it represents a water deity.

The Aztec sun stone was located in the ruins. this stone is 4 meters in diameter and weighs over 20 tonnes. It was once located half way up the great pyramid. This stone calendar was made around 1470 CE under the rule of King Axayacatl, the predecessor of Montezuma. this calendar is said to tell the Aztec history and prophesy for the future.

A colossal statue over a thousand years old that was thought to represent Tlaloc was found in the town of Coatlinchan Mexico. This statue was made of Basalt and weighed an estimated 168 tons. It was moved to the National Museum of Anthropology in Mexico City in 1964 on a special trailer with dozens of rubber tires. This didn't happen until they promised the residents of the town to provide a large amount of public works. Some of the villagers still attempted to sabotage the vehicle but the secular authority prevailed in the end. The village people lined up to watch the statue as it passed by. Then there was a large unseasonable downpour. The downpour continued through the night. Many people may have interpreted this as a sign from the Gods. Some scholars believe that the statue may not have been Tlaloc at all but his sister or some other female deity. source: Time Life Lost Civilizations series:Aztecs: Reign of Blood and Splendor (1992) p.45-47

New discoveries at Bimini??
Don't jump to conclusions yet but if additional confirmation is found mysterious-america.net may be on to something. This article is already being cut and pasted on other online "news" sources. If it is true I'm sure there will be additional dives to confirm it by other people.

Approximately 8,000 terra cotta statues of armed warriors were located in this tomb. The weapons were all chromium protected which was a technique that was not reinvented until the 1930's. These statues were buried with Emperor Qin Shi Huang when he died about 210 BCE. This may tell us much about the way they lived but the people who built them never received much if any benefit from their work. Qin Shi Huang went on a book burning binge so much of the story of how they were built was lost.

"The Great Bell Temple is located on the western outskirts of Beijing. The temple houses China's largest bell made in 1406 under the reign of emperor Yongle in the Ming dynasty. The bell is 7 meters (23ft) high, 3 meters (10ft) in diameter and 46.5 tons in weight. 17 Buddhist scriptures are inscribed on the entire surface of the Bell both inside and out, totaling 227,000 Chinese characters." source: essential-architecture.com

The Leshan Giant Buddha was built during the Tang Dynasty (618-907). It is carved out of a cliff face that lies at the confluence of the Minjiang, Dadu and Qingyi rivers in the southern part of Sichuan province in China, near the city of Leshan. 71 meters (233 feet) tall

These caves culminate at a large natural cavern where wooden walkways precariously wind up the rock face to hidden cliff-side caves and the giant Maitreya Buddha that stands more than 27 meters, or almost 100 feet, tall.

The mound is 486 meters long.
The diameter of circular rear mound is 249 meters.
The width of the triangular front mound is 305 meters.

Ishibutai has a rectangular chamber measuring 25ft by 11ft by 15ft high approached by a passage 38ft in length, and roofed by two capstones each weighing between 60 and 70 tons each. (10) Modern estimates place the largest stone at approximately 75 tons. This estimate didn't come from the most reliable source however the sites below both show pictures of the stones in question and they do seem to be about right.

This is a large stone structure approximately 11 meters in length, 8 meters in width, and 4.7 meters In height. source:asukanet.gr.jp The upper surface is flat, with a shallow trough and two square holes. Rough Estimate of volume 200 cubic meters weight 500-550 tons. These measurements might be a little high judging by the picture but not a lot. Even if it is only 400 tons it is enormous.
I'm not sure whether this was carved in place or whether it was relocated. It appears as if it may have been relocated it isn't in a rocky area. If this is true moving it would have been a monumental task since it is near the top of a hill.

The Yonaguni ceremonial structure was found of the coast of Yonaguni Japan in 1985. Since then it has been a major source of controversy. They clearly appear to be manmade to me i suspect you'll agree when you see the pictures. However if they are manmade it would almost certainly prove that many of the assumptions about the early development of civilization are wrong. Yonaguni has been submerged under water since the last iceage. If this was built by man it would have been built 8,000BCE or earlier. Some of the experts seem to be looking for a way to explain this without considering the possibility that there was a more advanced civilization earlier than previously believed.

Some people claim that these structures were carved out of rock on site which would mean that they wouldn't have had to move these rocks since it was made at a quarry.

The exception to this theory seems to be 2 Megaliths that appear to weigh at least 20 to 40 tons. Some experts have claimed that these 2 megaliths were precisely placed if so they would have been moved by ancient civilization at least 10,000 years ago. Another possibility is that the tides moved them. If this is true it is unlikely that they would have been placed in a precise location. Ocean tides certainly have moved colossal stones at times. The statues at Easter Island were once knocked over by a tidal wave and I have seen some multi-ton stones that were moved during storms by the tides myself.

The megalithic entrance tunnel leading to parallel megaliths may also include evidence of colossal stones moved. If you look closely you can see what looks like a joint on both sides of the entrance that appears to be to precise to be natural. they are both at the same height. If it was made by man I can't imagine how they got the stone on top in place. This is subject to confirmation though.

According to the Morien Institute there are more under water structures near by however they have yet to show pictures of these new sites. It appears as if major parts of history may have to be rewritten. However it will be necessary to confirm the details on this before the final verdict is in.

Gochang Dolmen Site
"This group of dolmen are the largest and most varied. They are known as the Jungnim-ri dolmens and are centered in Maesan village. The dolmen were built from east to west at the foot of a series of hills at an altitude of fifteen to fifty meters. Generally, the capstones of the dolmens average around are one to 5.8 meters in length and can weigh ten to 300 tons. 442 dolmen have been documented and classified based on the size of the capstone. This group is believed to have been constructed around the seventh century BCE." source: wikipedia.org
"The dolmen in Kanghwa (Ganghwa in new spelling) is a northern-type, table-shaped dolmen where ancestral rites were held. It is the biggest stone of this kind in South-Korea, measuring 2.6 x 7.1 x 5.5 meters." source: worldheritagesite.org
A cube 2.6x7.1x5.5 would be 101.5 cubic meters. If it was granite one of the harder and heavier stones; it would be about 3 tons per cubic meter. This would mean it is about 300 tons. However the Dolmen is not a cube. If these are the maximum dimensions it would probably be about 200-225. wikipedia.org cited worldheritage.org as a source so this is actually only one source that made this mistake.

Originally, there must have been many of them, although only ten with inscriptions still survive. Averaging between forty and fifty feet in height, and weighing up to fifty tons each, all the pillars were quarried at Chunar, just south of Varanasi and dragged, sometimes hundreds of miles, to where they were erected.

The Khajuraho Temples were built in the tenth century CE. There were originally 85 temples only 22 survive but archeologists have found partial remains of much more. There are an enormous volume of quality carvings famous for sexual explicitly. The stones were put together with incredible precision. The columns and architraves are made out of colossal one piece stones that are probably over 10-30 tons.
According to a recent episode of lost worlds on the history channel their masonry expert Alex attempted to recreate one of the statues that was only 3 or 4 feet tall. It took him 60 days. He didn't specify how many hours. Someone who specialized only in carving and did it all the time almost certainly could do it faster if they had the skill but in order to build so many statues so fast they would have had to have an enormous amount of highly skilled sculptures spending an enormous amount of time doing nothing but carving.

The baths cover an area of 200 hectares. there is probably as much stone if not more than the pyramid of Cheops however it was made out of much smaller blocks and built over a longer time. The citadel was 10 hectares and 12 meters tall. It had a volume of 1,152,000 cubic meters. the great Bath is 12x7 meters by 2.4 meters deep with a volume of 160 cubic meters. The lower town is 190 hectares 9 meters high with an estimated population of 40,000. source: "Seventy Wonders of the Ancient World" edited by Chris scarre 1999

"The town is 50 km from Hassan and 10 km from Chananrayanpatna. It has two hillocks, Indragiri and Chandragiri. The former one is also known as Vindhyagiri, and stands 143 meters high. About five hundred steps lead to the top of this picturesque hillock where 58.6 ft high Bahubali (Gomata) statue stands. It is a monolith carved around 980 A.D. and considered to be a landmark in the annals of world art. His broad shoulders are 26 feet across." source: kamat.com
The estimate of the shoulders is probably a little high but several other sources have confirmed the height and the fact that it was built out of a single piece of stone. The shoulders are probably between 23 and 26 feet wide. The Base seems to be about 33 feet wide. After making some rough estimates of the dimensions I'm estimating it is about 200 cubic meters. This is made out of granite which weighs about 3 tons per cubic meter. That would be about 600 tons. This estimate has a large margin of error since it is based on rough guesses and incomplete dimensions. It is almost certainly between 300 and 700 tons. There are some reference to it being erected and it seems highly unlikely that it would have been standing up naturally on the top of a hill. There are also reference to the steps being carved out of the rock. It was made out of the granite from the hill but it may still have been necessary to shift it a little bit or erect it.

In 1858 Henri Mouhot sketched the ruins of Angkor on a trip to Cambodia sponsored by the Royal Geographic Society. His sketches led to the discovery of Angkor by a lot of Europeans who were previously unaware of the Temples.
In 1864 and 1873 Louis Delaporte took trips to Angkor on expeditions sponsored by the French. He also sketched his trips including himself in at least 1 picture. This included pictures of them transporting colossal statues over 10 feet tall back to France on the river. Some of the many statues taken from the Preah Khan Temple and other temples were lost in the river when the rafts capsized.

At the beginning of the ninth century Jayavarman II rose to prominence over other rival Khmer rulers and established a new Mandala (country). He initially built a series of square single celled towers with tall stepped roofs on Mount Kulen. He later established a new capital called Hariharalaya and built even more there. Jayavarman II was one of many leaders who rose to the status of a "God".

Jayavarman II was succeeded by his son Jayavarman III and then King Indravarman I who built the Preah Ko and Bakong temples. The Bakong used 100 times as much construction material as any previous temple. Angkor temples were often surrounded by moats Indravarman built a huge water system that benefitted from the fish stocks of the Tonle Sap.

The first King to establish a temple (Phnom Bakheng) on the site of Angkor was Yasovarman who succeeded Indravarman in 889 CE. This is the first of many temples at Angkor that also served as mausoleums. they were built over a period of about 400 years. The Bakheng was on a rectangular base that rose in 5 levels. The Bakheng included 109 towers 5 main ones in the center and 104 distributed symmetrically over the lower 4 levels. This was supposed to have astronomical symbolism representing the heavens including the 12 year cycle of Jupiter.

Angkor Wat
When king Suryavarman II the last king built his temple he wanted to build the most spectacular one of all but there wasn't enough room within the walls of the old city which later became Angkor Thom so he built Angkor Wat outside the walls. It had as much stone as the Temple of Khafre, over 5 million tons of stone. Angkor Thom and other surrounding temples which were built over a period of 400 years probably have at least 10 times that. Angkor Wat was built on an enormous foundation of mostly small sandstones, sand and laterite slab blocks. The laterite blocks are similar to mud bricks. they are made out of a local soil which hardens when exposed to the air.

Angkor Wat was built between 1113 and 1153 CE. Building such a large monument as Angkor Wat in such a short tome is almost as tough as building the pyramid of Cheops in only 23 years. Assuming they really were built that fast which is hard to believe. That involves moving and carving and installing 370 tons of stone every day each step of the way. Virtually all of this stone including columns lintels even roofs were carved. the source shows some picture of columns that were not carved so this claim might be slightly exagerated but not much. Some have claimed that Suryavarman sacrificed quality for quantity but from what I've seen of the pictures it may not have been that much of a sacrifice since they still seem to be good quality. It also involves moving an even larger volume of fill for the foundation including small sandstones, sand and laterite slab blocks. As far as I know Angkor didn't have as many colossal stones as Giza but there were still an enormous amount of multi-ton stones including many that almost certainly weighed over 10 tons. This was built by a system of virtual slave labor. The temple wasn't completed until after Suryavarman died.

Angkor Thom
His massive building projects and conquests took its toll on the kingdom which fell into decline. In 1177 the Chams invaded. Eventually Jayaverman VII rallied the Khmers and defeated the Chams. Jayaverman VII reestablished the old city as Angkor Thom with a new temple in the center. His temple was the Bayon sitting on a stone terrace included 50 towers famous for their statues of Buddas face 1 on each side of each tower. The Mandela lasted another 150 years before going into decline. Angkor Thom is a is a small city almost 4 square miles full of large temples. Most if not all the temples have a stunning amount of statues and wall carvings. Some of these wall carvings included depictions of battles against the Chams. The joints between the stones were extremely tight fits. The sandstones for all the Angkor Temples had to be transported 25 miles from the nearest quarry by boat.

At the My Son complex, there was one temple constructed of stone, the foremost stone temple in Champa civilization was the centerpiece of the complex. In 1900 French architect, artist and archeologist Henri Parmentier went to Vietnam to study Cham architecture. While there he sketched the lavishly ornamented tower of Mi Son. The [[stele]] inscription reveals that the last stone alterations to this temple were made in [[1234]]. Today, this temple is no longer standing, although it once stood at over 21m, the tallest building in the complex. Evidence gathered from the surrounding area show that it was once part of the original temple in the 4th century. In 1969 the Vietcong used this tower as a hideout and mounted a radio transmitter on the summit. After US air raids failed to knock out the tower a commando team crept in and planted explosives. The blast reduced the tower to a pile of rubble. source: Time Life Lost Civilizations series: Southeast Asia: A Past Regained (1995)

In 1608 the Portuguese plundered a 20 ton bell from the Burmese and attempted to bring it back to Portugal. they dropped it in the river and it was lost. This bell was later replaced with a 23 ton bell.

On or about 1825 the British attempted to plunder the 23 ton bell from the Burmese. They dropped it in the river. they were unable to retrieve it. The natives managed to raise it back up and retrieve it by attaching a large volume of bamboo. They brought it back to the Pagoda with technology that was more primitive than what was available to the British.

I'm not sure how they calculated the weight of the first bell perhaps they weighed the remaining one and estimated the first based on the dimensions.

The width is 120 meters by 120 meters deep overall height is 32 meters.

Preliminary Conclusions

Whether this theory is right or wrong

Whether there is a researching God or not it would be a good idea to learn from our mistakes. It would be a good idea to learn that demagogues that lead us into war for all the wrong reasons shouldn't be elected to public office. It would be a good idea to organize information so that we have an accurate perception of reality to base decisions on. It wouldn't be a good idea to trust people that distort the facts more than we trust people that present them honestly in an organized fashion that could be confirmed.
