Battles of Alnwick

Alnwick castle is a Northumberland castle that has been under the control of the Percy Family (Dukes of Northumberland) since 1309. In 1309, when Henry Percy obtained the barony of Alnwick, a new castle was built around an existing Norman shell keep that had been built on the site some two centuries before in around 1096. The new design consisted of a curtain wall around the keep and had seven semi-circular towers. The Percy family were involved in incessant wars with the Scots. Alnwick Castle was used as a location for Hogwarts in the Harry Potter film Harry Potter and the Philosopher’s Stone.
