Tooting Bec Lido in south London is the largest pool in the UK at 91.44 metres long and 30.18 wide. Dating back to 1906, it was a built by unemployed people living in the area. The pool is open to the public from May to September; the rest of the year you can only swim if you are a member of the South London Swimming Club, which has managed the lido during the winter months since the 1990s Photograph: Open House

Brockwell Lido was built by the London council in 1937, applying the art deco style that was popular at the time. It is now a Grade II listed building Photograph: Open House
