Church of Saint Ignatius of Loyola in Prague, Baroque church building on Charles Square, Prague, Czech Republic.

The Church of Saint Ignatius of Loyola in Prague is an early Baroque three-nave basilica built from 1665 to 1678 by Carlo Lurago, with Martin Reiner completing it, on the corner of Charles Square and Ječná Street. Its cream facade carries a triangular pediment topped by a haloed statue of Saint Ignatius, and a tower with a green copper dome rises at the east end.

Construction began in 1655 under architect Carlo Lurago as part of a major Jesuit complex in the city. The building was completed in 1677 and became one of the most significant religious structures built by this order across Europe.

The church is named after the founder of the Jesuit order, reflecting its importance to this religious community. Inside, paintings and statues of saints fill the space with a solemn character that reinforces the building's spiritual purpose.

The church is located near Karlovo náměstí metro station, making it easy to reach by public transport. Visitors should dress respectfully, and guided tours are available during regular opening hours.

The gilded initials AMDG on the chest of the façade statue stand for Ad maiorem Dei gloriam, the Jesuit motto. The haloed figure was placed in 1671, and contemporaries objected that a full-body halo belonged only to Christ. The Latin inscription in the pediment carries a chronogram giving the year 1671.
