Hôtel de Ligne, building in Brussels, Belgium

The Hôtel de Ligne is a neoclassical mansion facing the Parc de Bruxelles, at 70-74 Rue Royale and 37-49 Rue des Colonies. Its cream-painted, white-rendered facade has rusticated ground-floor masonry, two upper storeys of white-framed multi-pane windows between pilasters, and a triangular pediment with a round oculus window. Two dormer windows sit on the roofline.

The building was completed in the late 1700s when neoclassical style was gaining popularity across Brussels as architects drew inspiration from Greek and Roman ideals. Since 2001, it has served as the seat of the Parliament of the French Community, transforming it into a center for regional governance.

The Hôtel de Ligne was built as a residence for wealthy families on one of Brussels' finest streets. Its neoclassical design with straight lines and symmetrical windows expresses order and refinement, reflecting how educated people of that time valued classical principles in their daily surroundings.

The Hôtel de Ligne stands at Rue Royale 70-74, facing Brussels Park, with a corner on Rue des Colonies. The Parliament of the French Community occupies it, so the interior is not open to individual tourists; the facade with its pediment, oculus and pilasters is seen from the pavement. Groups can request a visit through the parliament.

The building was bought by the Brussels tram company in 1897, then passed to a bank a year later; the French Community Parliament acquired it in 2019 after Ethias occupied it from 2001. Above the entrance, a banner reading "PRIX JEUNES ARTISTES EXPOSITION" hangs beneath three flags.
