Vauxhall Spring Gardens AKA Vauxhall Pleasure Gardens in West Kennington has the Vauxhall City Farm on its borders, as well as the Black Dog, the Tea House Theatre, and the Royal Vauxhall Tavern, whose customers spill out on to its edges. It is nicknamed Brokeback Mountain locally for its rugged scenery.
It is currently playing host to the Vauxhall Pleasure Gardens summer festival – details below (we borrowed the image from the excellent Tradescant Road blog).
The Museum of London have some info about the history of Vauxhall Pleasure Gardens here.
