NEHL - A coal shaft was sunk in this location at Spital Tongues during either the 18th or 19th century, and was in use until at least the 1850s. It is likely this shaft was connected to Spital Tongues Colliery which was just west near Hunters Moor, and was connected to the riverside by the Victoria Tunnel. The shaft is annotated as a mine entry by the Coal Authority.

When the area was redeveloped by terraced properties, a vacant plot was left between houses leaving the shaft in situ. It was probably because the ground was unstable and wasn't filled in.

Nowadays, the shaft still hasn't been built over. It's next to the car park at Mill House.
