Morialmé Castle (Château de Morialmé) and its farm were established by the Comte de Bryas in 1633. The estate comprised 536 hectares.
The château building is formed by a central block, built by Charles de Bryas in the late 17th century, between two Neo-classical wings, in the shape of an H. The central residential block consists of a long space of 10 bays two storeys high built of brick, standing on a basement of stone. The 'arms room' (salle d'armes) contains noteworthy stucco decorations representing trophies of arms, as well as various floral and plant motifs. In the centre of the front wall is a monumental porch with a sandstone tympanum bearing the de Bryas arms.References:
The Château d'Olhain is probably the most famous castle of the Artois region. It is located in the middle of a lake which reflects its picturesque towers and curtain walls. It was also a major stronghold for the Artois in medieval times and testimony to the power of the Olhain family, first mentioned from the 12th century.
The existence of the castle was known early in the 13th century, but the present construction is largely the work of Jean de Nielles, who married Marie d’Olhain at the end of the 15th century.
The marriage of Alix Nielles to Jean de Berghes, Grand Veneur de France (master of hounds) to the King, meant the castle passed to this family, who kept it for more than 450 years. Once confiscated by Charles Quint, it suffered during the wars that ravaged the Artois. Besieged in 1641 by the French, it was partly demolished by the Spaniards in 1654, and finally blown-up and taken by the Dutch in 1710. Restored in 1830, it was abandoned after 1870, and sold by the last Prince of Berghes in 1900. There is also evidence that one of the castles occupants was related to Charles de Batz-Castelmore d'Artagnan, the person Alexandre Dumas based his Three Musketeers charictor d'Artagnan on.
During the World War I and World War II, the castle was requisitioned first by French troops, then Canadian and British soldiers. The current owner has restored the castle to its former glory.
