This unusual proposition is the result of a millionaire’s whim to build an art deco mansion around a medieval Great Hall. The result is a venue like no other to host a characterful wedding. The striking domed Entrance Hall, with its carved-wood wall panels and retro furniture, is a great place to hold your reception drinks or even the ceremony itself. Then it's over to the aforementioned 14th-century hall for your wedding breakfast. If there's time between all the formalities, guests can go on a private tour of the venue, giving them the chance to take in its old billiard room, photographic studio and a wartime basement bunker.
