On one day every September we open our school gates to the public in celebration of Heritage Open Day – England’s largest festival of history and culture. This year it is being held on 19 September 2026. Join us to unearth the royal, political and social history of Claremont mansion on a self-guided tour (no booking required). Admission and tours are all free. The mansion is open from 10.00am-17.00pm for self-guided tours.
