Culzean Castle, Lowlands, Scotland. One of the most amazing, least visited, hidden castle in Europe. Part of the castle is also a hotel. A couple of rooms are opened for guests to stay in, which can be booked months in advance.
Eilean Donan castle, Scotland. The castle was founded in the thirteenth century, and became a stronghold of the Clan Mackenzie and their allies the Clan Macrae. In the early eighteenth century the Mackenzies' involvement in the Jacobite rebellions led in 1719 to the castle's destruction by government ships. Lieutenant-Colonel John Macrae-Gilstrap's twentieth-century reconstruction of the ruins produced the present buildings.
