Unbeknown to many people, Lima, the Peruvian capital is not only a city with traditional colonial and religious buildings but is also full of ancient temples, all of them from before the Inca Empire. Known as huacas, they are places of worship built out of mud. Some of them are 4,000 years old. Lima has at least 350 huacas. Many of them are derelict and other are threaten by urban development. The Peruvian Daily El Comercio has joined forces with anthropologists and architects to save those remarkable buildings. They have published an interactive map with 60 huacas in Lima.
