Knocknarea is a large prominent hill west of Sligo town in Ireland, with a height of 327 metres. On the summit of Knocknarea is a large cairn about 55 metres wide and 10 metres high, making it the largest cairn in Ireland outside Brú na Bóinne in Meath. Although it has not been excavated by archaeologists, it has many features of a classic passage tomb.
The cairn is flat-topped and several kerbstones can be seen on the northern side. It is believed to date to around 3000 BCE, during the Neolithic (New Stone Age). It is known in Irish as Miosgán Meadhbha (Meadhbh's heap), and in English as Maeve's Cairn or Maeve's Tomb. Meadhbh is a queen of Connacht in Irish mythology, who is believed to have originally been a goddess.
The ancient cairn is a protected National Monument. In recent years, archaeologists have warned that it is being eroded by hikers climbing on it and moving or removing stones. The large number of climbers is leaving scars on the cairn and may be destabilizing the tomb inside. Irish folklore holds that it is bad luck to damage or disrespect such tombs and that doing so could bring a curse.
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.
