This Cuzco corner presents a notable juxtaposition between ancient Incan and Spanish colonial architecture. Since the Incas worshipped their sun god, Inti, above all others, this temple in their imperial capital was the most important of the entire realm. It was here that they brought the idols of all peoples they assimilated, to offer them representation as they demanded allegiance in Cuzco. When the Spanish arrived, they tore down much of the temple and built a monastery on top of it. However, the walls that do remain provide stunning examples of pre-Hispanic engineering, particularly the rounded outer wall that can be seen from Avenida del Sol.
