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.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
