Parliament Buildings is home to the Northern Ireland Assembly, the legislative authority for Northern Ireland established under the terms of the Belfast Agreement 1998 (aka. the Good Friday Agreement).
The building was originally constructed to accommodate the newly formed Government of Northern Ireland, established under the Government of Ireland Act, 1921. The grounds of Stormont Estate (224 Acres at the time of purchase) cost approximately £20,000 and the cost of constructing Parliament Buildings came close to £1.7 million. The Prince of Wales, later King Edward VIII, declared Parliament Buildings open on 16th November 1932 on behalf of King George V.
The building is designed in Greek Classical tradition, constructed by Stewart Partners Ltd under the guidance of architect Arnold Thornley, from Liverpool. He was a man who paid great attention to detail with many of the features in Parliament Buildings having symbolic reference. One example of this detail can be illustrated by the length of the building for it measures exactly 365 feet wide, representative of one foot for each day of the year. Arnold Thornley later received a Knighthood from George V in recognition of his architectural work.
