I started this page to help me organise a categorised list of all ancient buildings, from Neolithic earth mounds, through stone monoliths, sites that feature cyclopean or polygonal masonry, to major buildings such as intact pyramids, and sites such as Gobekli Tepe. My main aim was to be able to list interesting sites by country or category as an aide memoir. After a few weeks of just creating a list, I find that I probably needed a database, as the list is extremely extensive. There are 200 pyramids in Sudan alone, and thouands across the world. So this endeavour has literally become a list, maybe in 20 years I shall have added some information to each page! Pictured: Possibly the largest pyramid in the world, Cholula in Mexico.

Polygonal Masonry is a very high quality wall or structure building with stone that does not require or feature mortar, where there is little or no gap between the stones.

As in the picture in the header above, these walls may be tens of thousands of years old, made with stones into the hundreds of tons, and not only do they survive, but you can't get a piece of paper between them still after all this time.

They demonstrate that our ancient ancestors had a very high level of skill and tooling, with the ability to move the stones, that is not possible today.

"... a wall constructed without mortar, using enormous blocks of stone. This technique was employed in fortifications where use of large stones reduced the number of joints and thus reduced the walls’ potential weakness. Such walls are found on Crete and in Italy and Greece." From https://www.britannica.com/technology/cyclopean-masonry

Dry stone walls found in the UK follow cyclopean criteria, aside form the fact that they are very small stones in comparison. The name originates from the classical Greeks who believed that only the Cyclops had the strength to move the stones of the size that made up the walls of Mycenae. Pliny's 'Natural History' attributed this to Aristotle.
