Subterranean London

Embankment underground station, London (Villiers Street exit)

Guided by Peter G.

 Short version. The "Cobra Room," Secret Tunnels, Bomb Shelters, Crypts, Lost Rivers and Trains & Drains  

Long version. Most of London is under London. The London we "know" is just the crust. There's another world down there. A fascinating, freakish, disturbing world. Everything from the squat, camouflaged, granite-hard redoubt where the last stand would be made against the Nazis to the ultra-secret "cobra room." Scope out that London under London with a guide who's like ground penetrating radar, who can show you the tell-tale ripples on the surface – vents, secret doorways, emergency exits, the "last stand" redoubt – and old familiar London will never look the same again. 

N.B., for safety and security reasons we will not be crawling through tunnels and wading through sewers! The walk is a ground-level survey – the topographical equivalent of a scan – of what's down there.
