NEHL - Stanley Street was the first ground NUFC's predecessor ever played. It was named after the street which no longer exists, and did so until they were renamed Newcastle East End. They only played at this ground for a few years before moving slightly north to Dalton St, which is now within the Byker Wall.

Stanley Street is actually the small section of Walker Road which remains between St Peter's Social Club and St Peter's Station, with the road only being built in 1870. It was previously the scene of multiple terraces, a number of churches and a large Corporation School for 350 boys, girls and 300 infants. This community that was fostered led way to the Stanley Cricket Club, later evolving into the football club to fill the gap over the cricket off-season.

The most likely location for the ground is the patch of land between Brinkburn Street and Bolam Way. This is in part thanks to the topography, and the locality of the chapel which was once situated where the social club has been built. This likely provided informal changing facilities for the players.

I've written a number of threads on the football club. You can see one here: https://x.com/neheritagelib/status/1695064233325572531?s=20
