From Teotihuacán

"This vista shows the so-called Avenue of the Dead with the Pyramid of the Sun on the left and was taken from the top of the Pyramid of the Moon. These enormous stone edifices, probably built by an ancient pre Columbian civilisation sometimes referred to, incorrectly, as the Aztecs but likely to be the Toltecs, is at the heart of a huge city complex at its height in about 200 after Christ. How it was done and why are mysteries". Taken by Mike
