Ravensworth Castle was erected towards the end of the thirteenth century, and has belonged successively to the Fitz-Marmadukes, Lumleys, Boyntons, Gascoignes, and Liddells. It originally consisted of four towers, one standing at each angle of a courtyard and joined by curtain walls. Two of these towers still stand and form part of the present castle, which was erected shortly after 1808, from designs by Nash. It may be added that the castle was formerly known as Ravenshelm, Ravensworth being the name of the adjoining village. Not far from the castle, and near to the road leading to the north entrance, is an old cross commonly known as the "Butter Cross." It is stated that the country people left their produce here for the citizens of Newcastle to take when that city was infested by the plague in the sixteenth century. [Illustration: THE CROSS AT RAVENSWORTH.] A few miles to the west, Gibside, a seat of the Earl of Strathmore, stands in an exceedingly picturesque position. A terrace at the back of the house stands above a sheer descent to an exceedingly wild glen. The older portions of the building were erected by Sir William Blakiston, who had inherited the estate from his grandmother, an heiress of the Marley family, in the reign of James I. Over the entrance are the Royal Arms, and the arms of Blakiston and Marley quarterly with the initials W. I. B. for Sir William and his wife Jane Lambton. There is also an interesting sundial inscribed with the motto _Ut hora, sic vita_. The old drawing-room has a large fireplace, with figures of Samson and Hercules at either side, and above a further heraldic display of the family alliances. There are four baronial mansions lying between the Wear and the Tees. Barnard Castle, once a residence of the princely house of Baliol, has for long years been a ruin. Originally erected by Bernard de Baliol, son of Guy de Baliol, Lord of Bailleul en Vimeu in Picardy, and founder also of Baynard’s Castle in London, it passed on the attainder of his descendant John Baliol, sometime King of Scotland, in 1296 to Bishop Bek. A few years later Edward I. severed the Durham fees of Bruce and Baliol from the control of the Palatinate and granted Barnard Castle to the Beauchamps. By marriage the estate passed to the Nevilles, and by marriage again to the Crown. Later it passed to the Vanes, who hold it still. The castle, which was of some size and great strength, stands in a commanding position above the River Tees. A great portion of the remaining buildings dates from Norman times. One of the towers is still known as the Brackenbury Tower, evidently deriving its name from the family of the famous Constable of the Tower of London. The castle is also associated with Richard III., whose badge of "the hog" occurs in one of the rooms.
