Sillustani Pre-Inca Cemetery (Tombs - Chullpas)
These ruins are located about 32 km from Puno, on the road to Juliaca and are one of the best in the region. These circular stone towers, the Chullpas, which overlook a small lake, are huge funerary monuments built by the Collas to keep their mortal remains. Each structure is at least 12 meters high. The way they were built, with a smaller diameter in the base than at the top challenges the laws of equilibrium.
