Parliament Hill Lido, located in Hampstead Heath, north London, is next to Gospel Oak railway station.

There is a users' group for the lido (and the ponds), the United Swimmers' Association of Hampstead Heath.

[1][2] Costing £34,000 to construct, this was the most expensive of the then London County Council's 13 lidos built in the 1920–39 period.

[citation needed] In 1976, after the death of a 15-year-old boy,[3] further safety measures were taken, including removing most of the diving facilities and increasing staff.

Refurbishments after the late 1980s included hot showers, cycle racks, a paddling pool and CCTV.
