The Jacques Delors building, at 99-101 rue Belliard in the European Quarter of Brussels, houses the European Economic and Social Committee and the Committee of the Regions. It sits between the Rue Belliard (Belliardstraat) and Leopold Park and was formerly called the Belliard building. It housed the Brussels activities of the European Parliament until the 1990s, when these functions were moved to the new Espace Léopold. In the 2000s, the building was renovated for use by the two Committees.
