Edinburgh Old Town has preserved much of its medieval street plan and many Reformation-era buildings. The 'Royal Mile' is a name coined in the early 20th-century for the main artery of the Old Town which runs on a downwards slope from Edinburgh Castle to both Holyrood Palace and the ruined Holyrood Abbey. Narrow closes (alleyways), often no more than a few feet wide, lead steeply downhill to both north and south of the main spine which runs west to east.
Notable buildings in the Old Town include St. Giles' Cathedral, the General Assembly Hall of the Church of Scotland, the National Museum of Scotland, the Old College of the University of Edinburgh and the Scottish Parliament Building. The area has a number of underground vaults and hidden passages that are relics of previous phases of construction.
The street layout, typical of the old quarters of many northern European cities, is made especially picturesque in Edinburgh, where the castle perches on top of a rocky crag, the remnants of an extinct volcano, and the main street runs down the crest of a ridge from it. This 'crag and tail' landform was created during the last ice age when receding glaciers scoured across the land pushing soft soil aside but being split by harder crags of volcanic rock. The hilltop crag was the earliest part of the city to develop, becoming fortified and eventually developing into the current Edinburgh Castle. The rest of the city grew slowly down the tail of land from the Castle Rock. This was an easily defended spot with marshland on the south and a man-made loch, the Nor Loch, on the north. Access up the main road to the settlement was therefore restricted by means of various gates and the city walls, of which only fragmentary sections remain.
The original strong linear spine of the Royal Mile only had narrow closes and wynds leading off its sides. These began to be supplemented from the late 18th century with wide new north-south routes, beginning with the North Bridge/South Bridge route, and then George IV Bridge. These rectilinear forms were complemented from the mid 19th century with more serpentine forms, starting with Cockburn Street, laid out by Peddie and Kinnear in 1856, which specifically improved access between the Royal Mile and the newly rebuilt Waverley Station.
Edinburgh Old Town is part of UNESCO World Heritage Site of The Old and New Towns of Edinburgh, inscribed by in 1995.
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.
