On the banks of the river Trent in Newark, Nottinghamshire this castle dates from the mid-12th century when it was built by the Bishop of Lincoln after being granted permission by King Henry I. The castle was initially of wood construction, later rebuilt as stone. King John died of dysentery after a feast at the castle in 1216 which indicates the kitchens may have needed work. The Bishop established a mint at the castle.
The castle was extended and rebuilt in the 14th century. Though the castle was slighted during the Civil War. The castle ruins were partially restored in the mid-1850s.
Today the gatehouse, part of the curtain wall and a tower survive.
