Newark Castle was originally a Saxon fortified manor house, founded by King Edward the Elder. In 1073, Robert Bloet, bishop of Lincoln founded an earthwork motte and bailey fortress on the site. From 1123-33, Bishop Alexander the Magnificent completely rebuilt the castle, when founding a prominent stone structure of ornate construction. In the late 13th century, the castle was substantially rebuilt with a new riverside curtain wall and after alterations in the 15th and 16th centuries, the castle became more of a palace. Slighted after it was held for King Charles I during the Civil War, sadly only the gatehouse, including chapel and lodgings, curtain wall and north-west tower now remains. 10 miles south-east at Hough-on-the-Hill is Castle Hill and 12 miles north-east is Somerton Castle.
