Maison Losseau

Maison Losseau is an Art Nouveau private house standing at number 37 rue de Nimy in Mons, Belgium, right next to the city's courthouse. Although the building itself dates back to the 18th century, its striking present-day appearance comes from a thorough renovation carried out in the early 1900s.

Who commissioned the renovation?

The transformation was carried out at the request of Léon Losseau, whose name the house still carries today. It was his commission that turned an ordinary 18th-century townhouse into one of the notable Art Nouveau landmarks of Mons.

Who designed the new facade?

The Art Nouveau renovation was the work of architect Paul Saintenoy, who reshaped the building's exterior and interior in the decorative style that was flourishing across Belgium at the turn of the century. His design gave the house the ornamental character that distinguishes it from its neighbors along the same street.
