If your after another south London history location, the tfl tour of the Clapham south tube bomb shelter is excellent if a little expensive
Ah, I grew up very close to that and as a child the structure, which is clearly huge, was a source of some mystery to me and my friends.
We were told that it was built during the war but never actually used as a bomb shelter during the war which always seemed weird to me as Clapham South tube station definitely was. In hindsight I now realise that it was was presumably built after the London blitz.
I know that it was used as a processing centre for migrants from the West Indies during the time of the Windrush generation, apparently the nearest labour exchange to it was Brixton which explains why so many West Indians settled there.
I didn’t know that it is now connected to TfL or that they now have tours so thanks for that.
