Exeter (or Rougemont) Castle was started in 1068. In 1136 it withstood a three month seige. The County Court was built on the site in the 18th century, but the city walls, a tower and the gatehouse still stand. Athelstan's tower is late 12th century, although the present turret is 15th century.
Danes Castle was built in 1136 to the west during the seige of Exeter. The earthworks have recently been found after being submerged under a reservoir.
