Construction started on this church of the Jesuit order in 1576 at Amarukancha or the Palace of the Inca Huayna Qhapaq. It is considered the best example of colonial Baroque architecture in America. The facade, all of carved stones, is spectacular. In the interior there is a beautiful gold altar, which is built over an underground chapel. The church also possesses a collection of sculptures and paintings, such as the wedding of Saint Ignatius Loyola's cousin and a Ñusta of Inca stock.
