Built between the years 1710 and 1734, this is the oldest colonial church in Buenos Aires. It is famous for being a place of resistance during the English invasions of 1806. The church has tunnels beneath which can be visited and stands out with its Baroque façade. Many influential 18th century paintings can also be viewed here, including the sliding canvas of San Ignacio de Loyola which dates back to 1767.
