Tambo Colorado, Pisco Valley. Southern Coast of Peru. Tambo Colorado ("Red Tavern") is doubtless the best preserved Precolumbian adobe structure in Peru. With the roofs restored it could quickly be put in pristine condition. This is due to the fact that it is on a very late horizon, the Inca period, possiblyabout a.D.1450,and is in a region which is almost absolutelyrainless. The walls still retain much red and yellow painted surface. Waullac, Huaraz. Northern Highlands of Peru. Throughout the highlands of Peru are masonry charnel houses known as chullpas. This one, in the suburbs of the city of Huaraz, has been slightly restored and maintained as a small park by the director of the Huaraz Museum, Dr. Agusto Soriano Infante, shown at the left.
