Place & story
The Hill family’s Georgian town
Wills Hill, first Marquess of Downshire, developed the house now known as Hillsborough Castle alongside terraces and public buildings around the square. Historic Royal Palaces describes it as a Georgian townhouse, originally facing a road and neighbouring shops rather than standing apart in a remote demesne. Later enlargement of the gardens displaced roads and buildings. The village’s layout therefore records both urban development and the subsequent expansion of an estate landscape around the house. [2]
The earlier fort
Hillsborough Fort was built in the seventeenth century to protect the road between Carrickfergus and Dublin and became an early home of the Hill family. Its later uses were more festive: in 1837 it hosted celebrations for Lord Hillsborough’s marriage, attended by thousands of guests. The fort’s history thus moved from defending a route to providing a setting for the estate family’s public entertainments, with its surrounding green remaining part of the village landscape. [3]
From market to courthouse
The courthouse began as a Georgian market house before 1765. From 1810 it accommodated court business, with the Grand Jury meeting upstairs. The same building therefore served both trade and the administration of justice at the village square. Its later exhibition use preserves a public function within a structure whose earlier activities were central to the estate town’s economic and civic life. [4]
A setting for political agreement
The British government bought Hillsborough Castle in 1925 for use as the Northern Ireland Governor’s residence. Its political role continued after direct rule began in 1972. Margaret Thatcher and Garret FitzGerald signed the Anglo-Irish Agreement in its State Drawing Room in 1985, and later negotiations at Hillsborough contributed to the peace process. In 2010 talks at the castle led to the Hillsborough Agreement on devolving policing and justice. The former family house became a recurring venue for negotiations affecting Northern Ireland. [2]
