Hillsborough Castle

Hillsborough Castle stands in the village of Royal Hillsborough in County Down. It is an 18th-century Georgian country house, not a true castle, built for the Hill family. The British government bought it in 1922 to serve as the official residence of the Governor of Northern Ireland. After the Governor’s post was abolished in 1972, it became the home of the Secretary of State for Northern Ireland. The castle also hosts the British monarch and other royals during visits to Northern Ireland. Historic Royal Palaces has managed the site since 2014. The castle has played a key role in Northern Ireland’s political history. It was here that the Anglo-Irish Agreement was signed in 1985. In 1999, Mo Mowlam opened the grounds to the public for the first time. Queen Elizabeth II stayed at the castle during her 2002 visit, and George W. Bush visited in 2003. Important talks have taken place there, including meetings between British and Irish leaders in 2010. King Charles III visited with Queen Camilla in 2022 to receive a message of condolence. Visitors find a grand house with elegant rooms and sweeping grounds. The estate includes a tree planted by the first Governor of Northern Ireland in 1925. The castle’s interiors reflect its long history, with spaces used for official meetings and royal stays. The gardens and pathways offer peaceful walks through well-kept landscapes. The site blends political significance with historic charm, making it a notable place to explore.
