OXFORD CIRCUS ST.

One of the most emblematic underground stations in London is Oxford Circus, where 200 million passengers come every year from the Central, Bakerloo and Victoria lines, eager to visit Oxford Street, the busiest shopping street in Europe. But its tunnels and corridors hide lesser known spots: clandestine meeting points during the war, anti-aerial shelters, a makeshift BBC studio, etc. Carry true story in your ears!
