Teotihuacán - Subestructura de los Caracoles Emplumados

A tunnel leads to part of what is probably the oldest building in Teotihuacán. Known as the Subestructura de los Caracoles Emplumados (Substructure of the Feathered Snails), it lies hidden away beneath the Palace of the Quetzal Butterfly. The largest of the remaining faáades, which once belonged to a temple, is decorated with superb reliefs. Snails decorated with colourful feathers (musical instruments?), green birds (parrots?) and four-leaved flowers are all visible.
