While much of European architecture can be studied and analysed from a modern perspective, there are several ancient architectural wonders that dot different parts of the world, which have no written documentation. The Pyramid of the Sun in the ancient city of Teotihuacán, Mexico is one such structure. Built about 100 CE, it is one of the largest structures of its type in the Western Hemisphere. The pyramid rises 216 feet (66 metres) above ground level, and it measures approximately 720 by 760 feet (220 by 230 metres) at its base.
The Pyramid of the Sun dominates central Teotihuacán, and stands on the main north–south artery of the city. It was constructed of about 1,000,000 cubic yards (765,000 cubic metres) of material, including hewed tezontle, a red coarse volcanic rock of the region. On the pyramid’s west side, there are 248 uneven stair steps that lead to the top of the structure. The sheer enormity of the structure makes one wonder at the architectural expertise of this ancient civilisation.
Archaeological explorations have revealed a system of caves and tunnel chambers beneath the pyramid, and other tunnels have been found throughout the ancient city. Based on the clay pots and figurines found in the ruins, experts believe this Pyramid too, like the pyramids of Egypt, may have served as a tomb.
