Blenheim Palace

Fancy hosting an event in a Unesco World Heritage Site? This grand Grade I-listed venue, the birthplace of Winston Churchill, can be booked for dinner, business or away days. 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 are good for drinks ahead of the main event. With its own private terrace, the Orangery is made for summer parties.
