The refurbished 1901 Royal Artillery Barracks houses an interactive exhibition on the ground floor, tracing the history of the castle, its people, and its links with Falmouth and the trade routes of the British Empire. A key feature is a hands on scale model of the castle: with the aid of special effects, children can step into the shoes of a soldier on kit parade.
On the first floor of the Royal Artillery Barracks, is an exhibition called Fortress Falmouth which includes memorabilia, letters, weapons and other displays which explore the lives and stories of the soldiers who trained and worked at the castle.
Pendennis Castle is also home to a collection of wartime cartoons by George Butterworth. The acclaimed cartoons, which appeared daily throughout World War II, lampooned both Hitler and Mussolini, enraging the Nazi leader so much that the cartoonist was put on his ‘hit-list’.
