Raqch'i (Quechua) is an Inca archaeological site in Peru located in the Cusco Region, Canchis Province, San Pedro District, near the populated place Raqch'i. It is 3480 meters above sea level and 110 kilometers from the city of Cuzco. It also known as the Temple of Wiracocha, one of its constituents. Both lie along the Willkanuta River.
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 adobewall 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. The foundations measure 4 metres (13 ft) for both the wall and the columns are classic high Inca stonework with the remaining height built of adobe.
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.
The Temple is the only Inka building for which we have an account of how people should walk through it. It is highly significant that the design of the building means that, on entering its two known doorways, progress of visitors is immediately blocked by a series of tall pillars that they are forced to walk around. If devotees took this as a suggestion as to how to proceed through the building, they would have begun to trace a path similar to a zig-zag motion. This could have been deliberate design; a way to express aspects of Inka cosmology in particular their relationship with Wiracocha. In processing through the temple, the devotees would have wound their way towards the statue of Viracocha, the volcano and the spring.
According to Inca mythology, Wiracocha came to the region the Inka called Kacha but the local people there did not recognize him and tried to attack him. When he them, he made fire fall from the sky and burn the hills around the people. The Kacha went to Wiracocha pleading forgiveness and he put the fires out and explained to them who he was. They built a wak'a (shrine) where Wiracocha had stood and gave him many offerings. When the Inka Huayna Capac passed by the province of Kacha he saw the wak'ashrine of Viracocha in the midst of the plain and he asked why it was there. The people of the province told him of the miracle that Viracocha had performed. He decided that the remembrance of this event should be greater and ordered the erection of the temple.
