Raqchi is the name of both the town and an Inca archaeological site in the Cusco region. The most prominent structure is the Temple of Wiracocha, an enormous rectangular two-story roofed structure that measures 92 metres (302 ft) by 25.5 metres (84 ft). This structure consists of a central adobe wall some 18 to 20 meters in height with an andesite base. Windows and doors allow passage. It is flanked on each side by a row of eleven columns.
Prior to its destruction by the Spaniards, the temple had what is believed to be the largest single roof in the Incan Empire, having its peak at the central wall, then stretching over the columns and some 25 metres (82 ft) beyond on each side. The huge proportions of the temple, and its prominence on the site explain why the whole complex is also sometimes referred to as the Temple of Wiracocha.
Other features of the site include living quarters, storehouses, a fairground, and baths.
