There was a colliery at Winlaton in 1366/7 when it provided Edward III with 576 chaldrons of coal for works at Windsor Castle. In the mid 16th century "Westmorland Colliery", i.e. all the coal mines in the manor of Winlaton, were leased for 30 years to Cuthbert Blunt who sublet to Christopher Cooke. The location of the - probably numerous - pits of this period are unknown.
