San Ignacio church was built by the Jesuits and inspired by the Church of San Jesus in Rome. It was one of the most important churches in colonial times and also one of the most beautifully decorated. The church was designed by Coluccini and has magnificent retables, tall naves, delightful Baroque altars, and a Renaissance-style dome. The church also has a large number of paintings by well-known colonial artists and outstanding carvings by Pedro Laboria, the great Spanish sculptor.
