Where the Ordnance Survey meets the school playground.

Every country has strange corners on its map, but Britain has a particular gift for place names that sound like a dare. In this episode of Peculiar Britain, we take a tour of the nation's rudest, silliest and most unfortunate signposts, from a Dorset hamlet named after an open sewer to a Cornish lane that warns you about your own neck. Along the way we dig into medieval prostitution, Old Norse farming terms, Victorian squeamishness, and the local communities who've had quite enough of tourists nicking their village signs.

Grounded in genuine etymology and historical record, but told with a wink, this is the story of how Britain got so rude by accident.
