Descend deep below the streets of South London and uncover a secret world frozen in time. On the Hidden London: Clapham South Subterranean Shelter tour, you’ll explore a vast underground maze built during the Second World War, once home to families seeking refuge from the Blitz.

Walk through tunnels lined with original bunk beds, explore the canteen, medical bays, and sleeping quarters, and hear the rumble of trains passing overhead.
