The Ruins of Clairmarais Abbey are a fascinating historical relic in Clairmarais, Hauts-de-France. This abbey was originally founded in 1140 by monks of the Cistercian order, led by Gonfroi, a follower of Bernard of Clairvaux. The abbey was dedicated to the Virgin Mary and was known as a spiritual and agricultural center in the region. Unfortunately, the abbey was dissolved in 1791 during the French Revolution, and only the ruins remain.

This cathedral, the former "Cloître Notre-Dame" of the canons, is the most beautiful religious building in the region. The shape and dimensions are impressive. The choir dates from 1200, the transept from the 13th century, the nave from the 14th-15th century. The 50 m high facade tower is decorated with vertical blind arches and crowned with watchtowers (15th century). On the middle buttress of the southern portal there is a statue of the Virgin Mary (14th century), and on the tympanum a Last Judgement with very few chosen ones. In the corner next to the choir there is an octagonal Romanesque tower.

You will see the tomb of St. Audomarus and the mausoleum of Eustache de Croy, chapter provost in Saint-Omer and bishop of Arras, a moving work by Jacques Dubroeucq (16th century). He shows the deceased kneeling, in bishop's robes, but also lying down and naked, as in classical antiquity. Note the 15th-century tombstones with inscriptions and the Descent from the Cross by Rubens (first bay of the right aisle). The tombs are 15th century, the alabaster statues 16th and 17th centuries. Other eye-catchers are the Madonna with cat (right aisle), the statue (13th century) of Notre-Dame des Miracles that attracts pilgrims every September, a Nativity of Christ from the 13th century and the tomb (8th century) of St. Erkembode, abbot of Saint-Bertin - here they leave shoes of children who have difficulty learning to walk. Above the astronomical clock (1558) a jaquemart tolls the hours (transept left). Above it is a rose window in flamboyant style. The statue group Grand Dieu de Thérouanne (13th century) stood 20 m above the portal of the cathedral of Thérouanne, which was destroyed by Charles V. The figures seem distorted, but the artist foreshortened them so that they had the correct perspective from below (transept left).
