Where is the actual Hogwarts located?
In real life, filming for scenes at hogwarts take place at Alnwick Castle and Gloucester Cathedral. The Duke of Northumberland, owner of Alnwick Castle, claims on his website: “We are fortunate and privileged in being a location for Hogwarts School in the forthcoming Harry Potter film.” Alnwick Castle is the second largest inhabited Castle in England, the first being Windsor Castle, and has been the home of the Percys, Earls and Dukes of Northumberland since 1309. The earliest mention of Alnwick Castle in the history books appears soon after 1096.
