The Broch of Burrian is an Iron Age structure, which stands on a small headland next to a rocky shoreline. It is separated from the hinterland by a series of defensive earthworks.
The broch has an external diameter of 18 metres and an internal diameter of 9.5 metres. The entrance passage is on the southeast side, and the walls are solid. There is a small room in the inner wall of the broch on the northeast side. The broch is surrounded by outer defences consisting of the remains of four concentric ramparts on the landward side.
The Broch of Burrian was excavated by William Traill, proprietor of the island, in 1870 and 1871. A large number of artefacts, including a significant quantity of worked bone objects, were discovered. In addition, a number of artefacts of early historic or Pictish date were found. These include a cross-slab with ogham inscription, painted pebbles and part of an iron bell of Celtic type. Part of a Pictish house was uncovered to the north east side of the broch. The finds are now in the National Museum of Scotland.
The evidence suggests two phases of occupation, both dating to the Iron Age. In the second phase, the broch was converted into a sort of wheelhouse. The second phase went on for a long time, as there were clear Pictish elements among the finds, from as late as the 7th to the 9th centuries AD. Two items (the cross-slab and the iron bell) suggest early Christian activity, although there is as yet no other evidence for monastic settlement.
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.
