1. Peckforton Castle, Cheshire
This vast, grand castle is a popular celebrity wedding venue. Unsurprisingly, it’s extremely luxe and has a spa. Grade I-listed and built in 1876 by a lord, it’s two miles from the ruins of the Medieval Beeston Castle, where legend has it that Richard II hid his treasure. Plus, Cheshire Ice Cream farm is nearby, which serves up probably the creamiest iced goods you’ll ever eat – a consolation prize for any guests whose treasure hunts are unfruitful. Rooms start from $325 a night for a classic double or twin room.
