 The abbey became prosperous towards the end of the 12th century when it received valuable endowments from Guillaume de Fuveau and Raimond de Baux.This wealth however provoked the envy of the Benedictines of Montmajour Abbey near Arles, who attacked Silvacane in 1289 and took the Cistercians hostage (they were later released, after much negotiation).In 1358 the abbey was plundered by the troops of the army of Aubignan, and from this time on its financial problems grew, until in 1443 the monks were obliged to abandon the abbey.
