Soleilmont Abbey (Abbaye Notre-Dame de Soleilmont) is an abbey of Trappist nuns (OCSO, or Order of Cistercians of the Strict Order) situated in the forest and commune of Fleurus, at Gilly near Charleroi, Belgium, founded, according to tradition, in the 11th century, and a Cistercian nunnery from 1237. The nuns were expelled as a consequence of the French Revolution in 1796, but re-established themselves in 1802. The community became Bernardine in 1837, and Cistercian again in 1919.
