American Independence and Hillsborough Castle

Highlighting the castle's role in this pivotal moment of history

In 1771, Benjamin Franklin visited Hillsborough Castle to meet Wills Hill, Secretary of State for the Colonies and 1st Earl of Hillsborough. Hillsborough Castle, as the location of their meeting, is sometimes wryly described as the birthplace of America. This year, Hillsborough Castle will mark 250 years since America declared independence from Britain by highlighting the castle's role in this pivotal moment in history.

Hillsborough Castle's State Dining Room has been renamed the Benjamin Franklin Dining Room for this year, after one of the most famous guests ever to have dined there. To commemorate Franklin’s visit, seven carefully selected objects will be on display in the room, each helping to tell the story of his time at the castle. Highlights include a copy of the Declaration of Independence, a portrait of Franklin himself, and a portrait of Wills Hill.

The Benjamin Franklin Dining Room

Explore the Benjamin Franklin Dining Room where seven remarkable objects reveal Hillsborough Castle’s unique connections to American history. On display until February 2027, the collection includes treasures on loan from the American Philosophical Society and the National Archives at Kew, alongside items from Historic Royal Palaces’ own collection.

Visitors can discover these extraordinary objects and explore the fascinating history behind them as part of our standard guided tour of the castle.

In the centre of the room is a long Georgian dinning table that looks like it's currently being setup for a lavish dinner party, silver cutlery and crystal are visible on the table top. A Waterford Crystal chandelier hangs above the table and the walls are green. Red and gold curtains frame the tall windows and full-length gold-framed mirrors hang between them. A large rug with a flax flower design covers the wooden floor below.
