Flint
Flint Castle stands beside the Dee estuary in northeastern Wales. Begun in 1277, it was one of the first fortresses built for Edward I in his campaigns against Llywelyn ap Gruffudd. Its distinctive great tower and riverside position guarded a new English foothold. In 1399 Richard II met his rival Henry Bolingbroke here and was taken into custody, an encounter later given dramatic life in Shakespeare's play Richard II.
