The Hôtel de Ligne is a prestigious building in the neoclassical style dating from 1778, converted into its present form in 2001, and which retains its soul thanks to a harmonious blend of classical and contemporary architecture.It is a building revitalised and given a new lease of life by its new areas, its transparency, its performance, and its functionality. The building offers parliamentary committee rooms, a hemicycle, a library, offices and reception rooms arranged around the two newly created atria. The Hôtel de Ligne has now become a modern centre for political decision-making and multicultural meetings.
