Knock Castle, also known as Caisteal Chamuis is a former stronghold of the MacDonalds. Currently the castle is in ruins; it consists of an old 15th century keep of which one part, a window, remains to some height with traces of later buildings.
The castle was constructed by the Clan MacLeod and later captured by the Clan MacDonald in the late 15th century. Ownership of the castle passed between the two clans several times. It was remodelled in 1596 by the MacDonalds. By 1689 the castle was abandoned and started to decay. Most of the stones were then used for nearby buildings.
It is claimed by tradition that the castle is haunted by a Green Lady, a gruagach - a ghost associated with the fortunes of the family who occupy the castle. The ghost will appear happy if good news is to come; if there is bad news she will weep. The castle is also said to have had a glaistig, a spirit which is said to have a particular concern with caring for the livestock.
There is no way to get to Knock Castle directly by vehicle. There is a private road just off the A851 that leads down toward working farm buildings. The trail to the castle can be found by following the road to a livestock gate. Hidden in the vegetation on the right side of the pathway is a small wooden picket gate covered with lichen. On the other side of the gate is a faint trail that will eventually lead across a river to the castle, passing in front of a very old red-roofed farm building. The easiest approach to the castle is by following the trail upward after passing the farm building. On the right hand side after the farm building are the remains of what appears to be a blacksmith's forge.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
