Oakwell, home of football club Barnsley FC is having some work done, which has uncovered some old brickwork. Thanks to Alex Otulakowski for spotting.
I think those gates are on the east end of the Ponty (ie facing the main car park and Pontefract Rd) and date back to the old Brewery Stand days - ie in no way part of the East Stand but simply a way into it.
I reckon that's part ofthe old ponty end wall that used to join onto the wall that ran round the back of brewery stand..........sithi.
A brick skin in front of original wall, obviously, been taken down to a level to probably put wall ties in to join to old wall
