Whittington Castle is a castle in northern Shropshire, England, owned and managed by the Whittington Castle Preservation Fund. The castle was originally a motte-and-bailey castle, but this was replaced in the 13th century by one with buildings around a courtyard whose exterior wall was the curtain wall of the inner bailey. As a castle of the Welsh Marches, it was built on the border of Wales and England very close to the historic fort of Old Oswestry.
