Priory of Val Duchesse

The Sainte-Anne chapel is part of the Val Duchesse domain although it is older than the Prieuré de Val Duchesse. There is no written record of the date of construction of the Sainte-Anne chapel. It is thought that some parts of this simple Romanesque construction can be dated to the 11th century. The chapel became the property of the municipality in 1796 and has changed hands twelve times since 1812. From 1802 to 1843, it was promoted to the auxiliary parish church of Watermael, but became too small and was replaced by the Church of St. Anne. It was deconsecrated in 1854. It was restored around 1915 under the direction of Canon Lemaire, professor at the Catholic University of Louvain.

The Abbey of Rouge-Cloître was built in 1366 as a hermitage. The priory was then built in 1374, on land granted by the duchess Jeanne de Brabant. In the 16th century, the monastery was one of the most prestigious in the Spanish Netherlands, Charles V often stayed there. However, at the end of the 16th century, during the Dutch revolt (from 1566), the priory was looted and the canons were forced to take refuge in Brussels until the end of the troubles. The monastery was definitively suppressed in 1796 with the suppression of the monasteries decreed by the French Directory.

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.
