It’s not every day you can host an event in a Unesco World Heritage Site. This monumental Grade I-listed venue in Oxfordshire makes quite the impact on invitation letters. As the birthplace of Winston Churchill, today the Churchills remain, inviting you to book a group for dinner, business or an away day. The Long Library – picture 10,000 books and an impressive Henry Willis organ – is the largest space, working best as a stately banqueting spot. The Saloon and Great Hall do it justice as spaces for a drinks reception ahead of the main event. With its own private terrace, the Orangery sounds like the spot for a summer party.
