Just stumbled across this…I used to live just down from here when at college at Camberwell and remember those stretcher railings…and the mounds of. The filled in air raid shelters behind them.Just up from this was the old Grammer school on the corner of the junction with Wilson Road ( across from the church). There were two emergency water supply signs painted (faded) on the wall…don’t know if any of this is still there now the shelter direction were still painted on the church wall down by ‘the Oval’ tube station.
My friend was lodging in a house just down from here at the top of Southampton Way,he showed me a large communal air raid shelter in the back garden..still had rusted remains of beds and gas masks in there…in this was in 1989.
