St. Clement's Church

The chapel of Boondael, built in the 19th century, is the third chapel built on this site. A first chapel was built in the 15th century as a place of worship for the villagers. The present chapel is a reconstruction of 1842 by the architect Pierre Vandenbranden. Today, the chapel is used for artistic and cultural activities.

The church of Saint Adrien was built from 1938 to 1941, to replace the chapel of Boondael as a place of Catholic worship, it is a parish church for the Catholic community of Ixelles. The church of Saint-Adrien is also a place of worship for the Maronite community (Eastern Catholics of Lebanon). The chapel of Boondael was desecrated and saved from demolition in 1927 by the intervention of the Royal Commission of Monuments and Sites.

Notre-Dame-des-Grâces Church, commonly known as the Church of Chant d'Oiseau, was built from 1934 to 1949 by architect Camille Damman. This neo-Romanesque church is part of a convent of Franciscans who also provide pastoral services. The first Franciscan Friars Minor who arrived in Brussels in 1228 built a modest chapel in 1244 to house a statue of the Virgin Mary, called "Notre-Dame du Chant des Oiseaux", nestled in a beech tree in a small wood on the banks of the Senne, outside the city walls.
