Rebuilt several times and featuring a completely restored interior, the church is still mainly in the Flamboyant-Gothic style (15C-16C). The magnificent west front is decorated with a profusion of delicately sculpted ornamentation. Above the arching of the right-hand doorway, St Geneviève holds a candle, which it is said the devil put out and an angel always relit it. Inside, you will notice the beauty and simplicity of the layout. Don't forget to go and see the Treasury, once the abbot's private chapel, its walls (16C) decorated with murals.
