The present Invermark Castle is on the site of a 14th-century castle. The castle belonged to the Lindsays of Crawford. It was designed to control Highland marauders. It was here that David Lindsay, 9th Earl of Crawford died in 1558. The present castle was built in the 16th century, and heightened in the early 17th century. The castle was abandoned in 1803.
The 16th-century castle was a three-storey structure, having a corbelled parapet and parapet walk. The additions were another storey and a garret, and a two-storey angle-tower. The castle walls have rounded corners. Two massive chimney-stacks have window-openings giving the garret light.
The entrance, at first floor level, was reached by a movable timber bridge or stair. The entrance, a rounded arch, which still has an iron yett, led to the hall, to which a small room is attached. A wheel stair was the only access to the vaulted basement. The turnpike stair by which access could be gained to the upper floors, which were also subdivided, no longer exists.
The entrance to the castle is barred and well above ground level, making the interior virtually inaccessible to visitors.
There are foundations of outbuildings to the east and south of the tower; material known to have been robbed from the site to build the parish church probably came from here.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.
