18. Charlier Hotel (Charlier Museum)

This remarkable Neoclassical mansion was built in 1844 on Avenue des Arts, originally designed as a "promenade" and today replaced by the inner ring road. With its choice location on what was a prestigious new artery between Rue Royale and the Botanical Gardens, the building has been a privileged witness to the urban development and continuous transformation of the capital. Between 1890 and 1892, Victor Horta was given the task of adding a large exhibition space to replace the former stables, before continuing with a second extension, also in Neoclassical style, on the neighbouring plot of land. Today, the building houses the Charlier Museum which boasts a rich collection of works by Belgian artists (Anna Boch, Constantin Meunier, Auguste Oleffe…) and which will exceptionally be open on a weekend on the occasion of the BBN 2024.
