Stormont Castle is a mansion in east Belfast which is used as the main meeting place of the Northern Ireland Executive. It was never a castle as such: the original building was reworked in the nineteenth century in the Scottish baronial style with features such as bartizans used for decorative purposes.
Between 1921 and 1972, it served as the official residence of the Prime Minister of Northern Ireland. However, a number of prime ministers chose to live at Stormont House, the official residence of the Speaker of the House of Commons of Northern Ireland, which was empty as a number of speakers had chosen to live in their own homes. It also served as the location of the Cabinet Room of the Government of Northern Ireland from 1921 to 1972.
Before devolution it served as the Belfast headquarters of the Secretary of State for Northern Ireland, Northern Ireland Office Ministers and supporting officials. During the Troubles, it was also used by MI5 officers.
The castle is open to the public each year on the European Heritage Open Day weekend.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
