Hillsborough Castle in Northern Ireland will be exploring its links to the American Revolution. 

The 250th anniversary of American Independence is being marked at Historic Royal Palace’s Hillsborough Castle and Gardens in Northern Ireland with a special display and series of tours this year.

The castle’s connection to the events leading up to the American Revolution isn’t widely known so this is a great chance to discover its role.

In 1771 Benjamin Franklin visited the castle to meet the castle’s builder and Secretary of State of the Colonies Wills Hill. The pair discussed American affairs but their goodwill was short lived.Hill later resigned and blamed Franklin for his political troubles.

From April groups will find out more about the historic meeting, see the room and an array of letters, portraits and other artefacts.

Groups visiting Bowood can see a new exhibition in the house about the links with Benjamin Franklin and American Independence. 

A new exhibition at Bowood House in Wiltshire will also mark the 250th anniversary of the Declaration of Independence. 1776: Secrets, Spies and the American Revolution will delve into the world of 18th century espionage, something Benjamin Franklin, who was a friend of Bowood’s Lord Shelburne, played a huge part in.

Discover how the Americans and British both used ingenious methods to carry secret messages, from using invisible ink to hiding notes in unsuspecting places. Groups benefit from discounted rates, free coach parking and free admission for the GTO (self-guided visits only) and the coach driver (if applicable).

Groups can see a special anniversary exhibition in Scarborough this year to mark the 400th anniversary since it became a ‘seaside town’. 

The water was believed to heal ailments and a book published in 1660 about the spa waters was said to be a huge catalyst for tourists visiting ‘Scarborough Spa’.
