Northern Ireland’s royal residence

From grand family home to charming royal residence, Hillsborough Castle has welcomed the world and witnessed pivotal moments in history for over 300 years.

The castle is the official Northern Ireland residence of His Majesty The King. Leading members of the Royal Family have visited Northern Ireland regularly since 1922, using Hillsborough as their ceremonial and personal base.

The castle has also been home to the Secretary of State for Northern Ireland since the 1970s and has played a central role in the peace-building process for 40 years, including the Good Friday Agreement negotiations.

The Benjamin Franklin Dining Room

The magnificent State Dining Room has become The Benjamin Franklin Dining Room this year to highlight the 250th anniversary of the US Declaration of Independence. A very special collection of objects relating to the renowned statesman are on display to mark the occasion.

American Founding Father, Benjamin Franklin visited Hillsborough Castle in 1771 to discuss American colonial matters with Lord Hillsborough, Secretary of State for the Colonies at the time. He would have dined in this room during his stay.

Seven remarkable objects tell the story of Franklin and Hillsborough’s turbulent relationship and events leading up to the American War of Independence.
