All are welcome to join CoolTan Arts for a fun, guided midnight stroll through London on the midsummer solstice.
The walk theme is 'Light' so bring along torches, lamps or glowsticks and dress to impress!
Along the way there will be short talks on London's secret history - including tales of Charles Dickens' night walks and the resurrection men.
There will also be a midnight feast at a secret location with food kindly provided by the Breakfast Club.
Walk ends 5am Sunday at the Maudsley Hospital in Denmark Hill.
The Largactyl Shuffle Midnight Walk is an annual event but it is also part of a larger scheme, the monthly CoolTan Arts Largactyl Shuffles, which are guided, stigma-busting cultural walks designed to encourage mental and physical wellbeing, through art, exercise, humour and history.
