Iglesia de San Saturnino, Santiago de Chile, Gothic Revival church in Yungay district, Santiago, Chile.

The Iglesia de San Saturnino is a Gothic Revival church beside Plaza Yungay, built of brick masonry with a bell tower above the choir. Inside, a rectangular plan has a central nave and two side aisles, with wooden pillars and a wooden ceiling.

Construction began in 1844 under priest Luis Benavente and was completed in 1887 by architect Teodoro Burchard. The church was built on the site of a former prison.

The church takes its name from Saint Saturninus, invoked as Santiago's patron against earthquakes. The wooden image venerated inside was brought from Quito by Bishop Gaspar de Villarroel and previously stood in the Church of San Francisco before being moved here after the 1887 inauguration.

The church is located on Santo Domingo street next to Plaza Yungay and reopened in 2019 following major restoration work. It sits in a central part of the neighborhood and is easy to find.

An organ built by Oreste Carlini in the 1920s remains functional inside the church and produces beautiful sound during services. Metal reinforcements were added throughout after the 1985 earthquake to strengthen the structure.
