Kelly's Directory 1919 states "In the year 1281 Anthony Beke, or de Bek, Bishop of Durham, obtained a license from Edward I. to crenellate his mansion at "Saubretonne," or " Somerton," in this parish, which he afterwards presented to the king, who committed its custody to Henry, Lord Bellamonte;
King John I. (Le Bon) of France, taken prisoner at the battle of Poictiers, September 20, 1356, and afterwards a captive in England, was confined here from Saturday, August 4, 1359, to Saturday, March 21, 1360, when he was removed to the Tower of London;
the remains of this castle are very extensive, and a portion, together with some modern erections, form a commodious mansion and offices, now the property of George Frederick Ogle esq. and occupied by Messrs. Stickney and Thorne:
the castle area 330 feet by 180 feet, was inclosed by outer and inner moats and at the angles are the remains of four circular towers, formerly connected by intermediate buildings, and forming a quadrangular pile:
the south-east tower, still nearly entire, is surmounted by three pinnacles and a spire-shaped roof:
the south-west tower is in ruins and the north-west tower has been taken down ; that at the north-east angle has a curious groined roof, supported by an umbilical pillar, from which spring twelve arches, each forming a niche in the wall, in every one of which there appears to have been a Pointed window; the later buildings are partly Elizabethan :
the double moat is still extant"
