Wylam Colliery is marked on the first edition Ordnance Survey map of about 1860.

NEHL - Considering the size of Wylam in the early 19th century, it is staggering just how much activity went on here. The village featured at least three pits at one time, with the 1850s still hosting the Haugh Pit,. Peggy Pit and Ann Pit. The Peggy Pit served as an air shaft for the Haugh Pit by the mid 19th century. The complex was connected to the Newcastle to Wylam Railway, and had all the features you would expect of a modern colliery - pit pond, extensive pit heap and internal tramway network.

The illustration below by J W Carmichael shows the Haugh Pits and Peggy Pits on the other side of the river, with the Newcastle & Carlisle acting as the focal point.
