The Stannary Palace, also known as the Duchy Palace, circa 1265–1300, was a complex of buildings constructed by the Earls of Cornwall as the centre of their administration. The surviving exchequer hall is reputed to be the oldest non-ecclesiastical building in Cornwall. The much larger great hall, of which large parts remain, was built as a replica of Westminster Hall. Its original function was as a court and place of taxation dealing with the Cornish tin industry. The Earls of Cornwall and later, after 1337, the Dukes of Cornwall had their residence at Restormel Castle so the original name would have been the Stannary Hall or the Great Hall of Lostwithiel. After 1337 it was sometimes referred to as the Duchy Palace.
