Built by Jacques d'Abancourt in brick and stone in the Renaissance style, on the site of the house of the "Colombier", the hôtel d'Abancourt (1559) with its round tower was extended in 1608 by Jean de Montmorency, who added a square building in the same style with a square tower.
It finally saw itself become a home for Carthusian monks in the middle of the 17th century, via the construction of a chapter house and a small cloister (1663), a refectory (1687), the prior's lodgings (1690) and finally - after a large cloister and cells which were demolished in the 19th century - a chapel in the Jesuit style (not restored yet).
Built in the classical style at the start of the 18th century, the complex's church is made up of a vast nave and five side chapels.
After a six-year restoration campaign, this church was used to display objets d'art and sculptures to the public, with the 19th century sculptures in the nave and objets d'art in the side chapels, including medieval goldwork and a series of bronzes and terracottas by Giambologna, who was born in Douai.
