One of Belgium’s most famous monuments, the Lion’s Mound, is actually located within the municipality of Braine-l’Alleud. This route also includes the Berlaymont School complex and the Argenteuil Estate, which is now home to the Scandinavian School of Brussels. The estate also features the Queen Elisabeth Music Chapel, a modernist building, where the twelve finalists of the Queen Elisabeth Competition go into seclusion for one week to prepare for the final. La Hulpe sanatorium is located a bit further down the road.
