If you've watched a "Harry Potter" movie, you've seen Alnwick Castle in Northumberland intermittently play the role of Hogwarts Castle. Several destinations on the East Coast provide a worthy facsimile of the Cotswolds. You won't find the idyllic pastures, peaceful rivers, and quaint stone villages all in one place.
