Where was Mother Clap's Molly House? Do you know which borough holds the title of Porn Capital of Britain? And where should you enrol for 'rubber technologist gives full training on her rack'?
These and 37 other prurient pursuits are drawn together in a new map of Filthy London.
The map is largely concerned with the central area — erogenous Zone 1, if you will — from the many seductions of Soho to a pub on Whitehall that still holds a never-revoked brothel licence beside its alcohol licence.
The sleazy suburbs get a look-in, too. Find the best dogging spot with Thames views, the capital's last sex cinema (now closed), and — one for completists, we think — the love nest in Earl's Court where David Mellor had his toes sucked.
All human desire is laid bare in this new map from Herb Lester Associates for just £4. If you like what you see, we can also recommend the London gift pack, which includes four of the company's more recent maps and books, plus a unique handkerchief. It's not clear if that latter item is deliberately complementary to exploring filthy London.
