Tiverton Castle is a Norman stone fortress, founded in 1106 by Richard de Redvers. Early in the 14th century, Hugh de Courtenay transformed the castle, by encasing a quadrangular court with a curtain wall. Flanked on the four angles by towers, with the square two storey gatehouse flanking the east curtain wall. After Civil War slighting, only three sides of the court and the two southern angle towers remain. The round tower with a later conical roof is complete but the larger square tower is ruinous, they stand against the steep banks of the River Exe, with the other three sides originally having wet defences. 15 miles south is Exeter Castle.
