Today i headed down to London for another Hidden London tour, this time the former air raid shelters at Clapham South. Eight of these deep level shelters (Clapham South is 11 stories down) were built to protect people in the WW2 Blitz though by the time they were completed the Blitz was over - however they were used to shelter people during the V-1 and V-2 attacks on London later in the war.
Postwar they were used as cheap hotel accommodation and temporary housing for recently arrived immigrants. In recent years they have been used for document storage but nowadays the Clapham South shelter is just used for tours. A very good tour it was too, though the 180 steps to climb back up the surface did test me! You can see my photos here.
