The castle known as the "abbey" of Solières has its origin in 1214 when it was the seat of a mixed brotherhood of the orders of Saint Augustine from 1230 to 1261 and Saint Bernard from 1230 to the end of the Ancien Régime.
The abbey was dissolved in 1795 during the French Revolution and sold off as a national asset in 1797.
The church and most of the conventual buildings were demolished but the purchaser of the abbess's residence, built in 1658, converted it into a mansion for his own use, from which time it was known as the Château de l'Abbaye de Solières.
In 1935 it was purchased by the insurance co-operative of theBelgian socialist Party , who used it as a home for mentally and physically handicapped boys, under the name L'Heureux Abri.
