Tiverton Castle is the remains of a medieval castle dismantled after the Civil War and thereafter converted in the 17th century into a country house. It occupies a defensive position above the banks of the River Exe at Tiverton in Devon.
During the Civil War the Castle was a Royalist stronghold. Fairfax's Parliamentarian troops laid siege to a troop of Royalists within the Castle and set up his headquarters at Blundell's School and stationed his artillery on Skrink Hills (or "Shrink" Hills) just above him and below Cranmore Castle, about half a mile from Tiverton Castle. The Culverin, the largest artillery piece used by the New Model Army, was capable of firing up to 2,000 yards. Whilst they were still finding their range a lucky shot hit one of the chains holding up the Castle's drawbridge and a small party of roundheads were able swiftly to gain entry and thus put an end to the siege almost before it had started. The bulk of the defensive structure was then demolished by Parliamentarian troops to prevent any military re-use of the structure.
