Chillingham Castle was originally a fortified 13th century manor house, founded by the Grey family. In 1344, Sir Thomas Grey was granted a licence to crenellate and he founded the stone quadrangular castle, which is flanked by square angle towers. In 1536 during the 'Pilgrimage of Grace' rebellion, the castle was besieged and damaged by cannon-fire, when being held by Sir Robert Ellerker. Over the centuries, this compact castle of the northern plan, has seen considerable alterations to the buildings ranged around its central courtyard. Chillingham comes complete with a torture chamber and is the most haunted castle in England. Visit pending. 13 miles south-east is Alnwick Castle.
