This abbey church, built in the 12C and 13C, is as large as a cathedral and contains a host of works of art. Beneath the right-hand transept is the late 15C Dormition of the Virgin; inside the chapels there are magnificent sculpted partitions and the tomb of Abbot Thomas de Saint-Benoît, who died in 1307. The Chapel of the Virgin, an independent ensemble in the Flamboyant style, has fine stained-glass windows dating from the 13C to 16C. Opposite the chapel is the white marble tabernacle of the Precious Blood.
