Barley Pound is a large 11th century earth and timber ringwork and baileys fortress, founded by the bishop of Winchester. The inner ringwork, resembles a low flat-topped motte, which is due to the demolition of its encasing rampart and a 12th century flintwork masonry wall. All the four baileys, which give defence the north, west and south, are encased by ramparts, with ditches and counterscarp banks. This fortification may be Lidelea Castle, which was mention in the Gesta Stephani for 1147, when it was captured by King Stephen. After its return to Henry of Blois, it was dismantled and abandoned, in favour of the more powerful Farnham Castle. To the east is Powderham Castle, one of two 1147 siege-castles.
