Dating back to the 16th century, the mill was once the largest wool mill in the world - and a notorious workhouse.
Children as young as six were made to work there and - due to the appalling conditions - many workers lost their lives.
Some of those souls are thought to still haunt the the building, and there have been countless spine-tingling reports of a lost child heard crying, and of a lady in a black dress roaming the building.
Ghosts at Temple Newsam
Temple Newsam is said to house ghosts including those of Phoebe Gray and the so-called “Blue Lady”, Mary Ingram.
Phoebe was a young maid who was working at the great house in 1704, the night of a party to celebrate the victory of the Duke of Marlborough at the Battle of Blenheim. Phoebe returned from taking a drink upstairs via the back staircase, and was stopped by estate worker William Collinson, who was determined to steal a kiss.
