Gleaston Castle is seen looking east from the road known as Gleaston Lane which links the Urswick villages with Gleaston.  The construction of the south-west tower of the castle was begun around 1297 by John de Harrington I, Lord of Aldingham and Muchland.  The castle seen in the photograph was constructed between 1325 and about 1340.  The de Harrington family were the occupants of the castle until William de Harrington died without issue in 1457.  Following this, over a succession of owners, the castle decayed until today it is unsafe to enter.
