The most ornate and beautiful of all. Built by Jesuits between 1605 and 1765, this church is the pinnacle of Latin American Baroque. The church is known for its gold plated interior built by artists from the Quito School, who skillfully carved and gilded every inch of the Church with 23-carat gold sheets. My biggest regret is that photography was not allowed, meaning I am going to basically forget that I have ever been here. However, the exterior was not off limits, so we were able to photograph the lovely green and gold domes atop the church.
