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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
