Alnwick Castle, one of the largest inhabited castles in Europe - home to the Duke of Northumberland's family, the Percys, for over 700 years. In a rather pretty mode with the daffodils out, but it saves buying the postcard. The castle was used as a film set for the exterior and interior of Hogwarts in the Harry Potter films. We visited the gardens and the castle, rather expensive and the gardens are too new for my taste, but the state rooms of the castle really do make you feel you are visiting a living family property unlike so many National Trust properties with bits set aside and roped off for visitors. No sparing of the fine carpets here.
