The substantial ruins of Barnard Castle, which gave the town its name, cling to an aerie overlooking the River Tees. From the outside it looks satisfyingly complete from the right angle; inside it's mostly just a shell. You can see parts of the 14th-century Great Hall and the cylindrical, 13th-century tower. Look for the figure of a carved boar high on the wall of the inner courtyard—it was the family emblem of King Richard III (1452–85), placed there during his reign
in honor of the elevated status he bestowed upon the castle.
