Egremont Castle is an early 12th century earthwork motte and bailey fortress, founded by William de Meschines. The top of a hill, was steeply scraped to make a circular motte, with the remaining platform becoming a rectangular-shaped inner bailey. In the mid-12th century, William fitz Duncan founded the stone castle, when encasing the inner bailey with a curtain wall, flanked by a square gatehouse. In 1315 and 1322, King Robert the Bruce raided and damaged the castle, additions and alterations were then made, which included building The Great Hall. In 1572 the castle was dismantled, after Thomas Percy, 7th earl of Northumberland was executed for treason. 7 miles north is Moresby Hall.
