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