Best castles in Gloucestershire
4 castles in Gloucestershire, and every one of them comes with a bed. At Thornbury and St Briavels you sleep inside the walls: a Tudor castle begun in 1511 for the Duke of Buckingham and run as a hotel today, and a YHA hostel behind the twin-towered gatehouse Edward I added in 1292. Berkeley, held by the same family for around 900 years, and Sudeley, where Katherine Parr is buried in the grounds, let cottages on their estates instead. Thornbury is the one to check before you travel: it is a working hotel, so there is no way in without a room or a table booked.
