Attributed to architect Barnabé Guimard, this neoclassical building with a centred triangular pediment was built around 1777 for the Comte de Lannoy, as a symmetrical counterbalance to the other building at the corner of Rue des Colonies/Koloniënstraat. The edifice is part of the vast complex centred around Parc de Bruxelles/Warandepark (mainly in Rue Royale/Koningsstraat and Rue de la Loi/Wetstraat). In 1834, the building was occupied by the Prince of Ligne and became known as the Hôtel de Ligne. It was bought in 1897 by Brussels' tram operator Tramways Bruxellois, and then by a bank in 1900. In 2001, after a number of alterations and a complete renovation, it became the seat of the Parliament of the French Community. It retains several historic reception rooms with elegant original stuccoed ceilings that evoke the neoclassical or Louis XVI style. The Hôtel de Ligne is a focal point of contemporary political life, with numerous committee rooms and a parliamentary chamber.
