NEHL - Greenside's last pit was situated on what's now the village green from the mid 1900s to 1966. There was previously an A Pit and a B Pit located either end of the settlement which were both disused by the time this working was fully operational, and likely superseded them given they were both cramped. I imagine opening this new working brought about greater efficiencies and better technologies, especially given the abundance of sidings and the direct link to the Stargate waggonway down to the Newcastle & Carlisle line. This was possible as the Stella Coal Co took ownership of the working here, who also owned the Stargate and Addison collieries.

The working was a very typical 20th century colliery, though unusually had a conveyor over the road into the shaft previously known as the A Pit. Could would be transported aerially into the screens then shipped via wagons north to the Tyne. The colliery enabled further housing developments in the Greenside area as well as extra amenities. Clubs, halls and sports grounds all developed concurrently with the pit.

Nowadays, the complex has been flattened and is now a pleasant green. There is little to no sign of the working today.
