Tooting Bec Lido is an open-air fresh water swimming pool in South London. It is the largest fresh water swimming pool by surface area in the United Kingdom, being 100 yd long and 33 yd wide.
The Lido is on Tooting Bec Common between Tooting and Streatham. An original condition of construction was that it should be concealed from views across the common by a surrounding earth ramp. This ramp is now largely covered with bird-filled trees, except where it is breached by the new entrance.
The alternating bright red, yellow, and green doors of the changing cubicles seen above the turquoise water make the Lido a popular location for advertisement "shoots" and other filming. Brad Pitt's boxing "pool" scene in Snatch was filmed at the Lido.
