It's distinctive. You definitely know you're in Soho come sunset thanks to the thousands of neon signs lighting up the dark, narrow streets. And you've got the late neon artist, Chris Bracey to thank for some of the most iconic signs. He created provocative signage from the 1970s onward, not only for Soho but for futuristic films like Blade Runner.
As well as seeing some of his signage in Soho - you can visit the family-run Gods Own Junkyard in Wathamstow and buy your own bit of neon history.
Soho used to be one of the most notorious and densely populated parts of London in the nineteenth century. You can still see the evidence in the streets, with their tightly-packed buildings and network of alleyways (see Great Windmill Street below).
