Church of Saint Joseph, Catholic church in Waterloo, Belgium

The Church of Saint Joseph is built of reddish-brown brick with grey stone trim. A green copper dome sits on a rounded brick drum pierced by small round windows and is topped by a lantern with arched openings and a cross. On the left a slender pointed spire rises, and the front facade projects forward with a triangular pediment carried by four tall columns above a stepped base. The interior was rebuilt in white stone and stucco, with Ionic pilasters supporting a heavy entablature.

A forest chapel dedicated to Saint Anne burned down before 1687, and the people of Waterloo could not afford to rebuild it. Governor-General Don Francisco Antonio de Agurto, Marquis of Gastañaga, funded a chapel to Saint Joseph as a vow for an heir to the childless Charles II of Spain. The first stone was laid on 26 June 1687, and the chapel was inaugurated on 19 February 1690.

The church is dedicated to Saint Joseph, patron saint chosen by governor Don Francisco Antonio de Agurto as a model for King Charles II of Spain. Memorial plaques inside recall British officers who fell at the Battle of Waterloo on 18 June 1815, several referring to Restalrig barracks in Edinburgh, home of the Scots Greys. The carved oak pulpit and communion benches came from the abbey of the Blanches Dames at Aywiers.

The church stands on the chaussée de Bruxelles, the old road through Waterloo. The 1823 brick hall extends the dome to the rear, so the choir lies behind the dome rather than under it. The building is closed off towards the street, and the entrance is through the neo-classical west front.

During the French Revolution, a Parisian businessman attempted to dismantle the structure and sell its materials. This plan failed due to strong resistance from local people.
