Penrith Castle was originally a stone tower house, with a courtyard encased by a wide ditch. In 1397 and 1399, William de Strickland founded the quadrangular castle, when he was granted licences to crenellate his chamber and mantlet. The Neville family, added the Red Tower early in the 15th century and from 1471, Richard, duke of Gloucester transformed the castle, by adding a new gatehouse and an impressive range of lodgings around the courtyard. The layout of the castle can still be seen but sadly only parts of the curtain wall and towers, stand to any height. In the centre of town is Dockray Hall and 2 miles south-east is Brougham Hall.
