An English lido is a public outdoor swimming pool and surrounding facilities. On a cruise ship the lido deck features outdoor pools and related facilities.
The term comes from Lido, the Italian word for “beach”, and may have found its way into English via English visitors returning from Italy where sea-bathing took place from the late-19th century.
Saltdean Lido in the city of Brighton and Hove, is an Art Deco lido designed by architect R.W.H. Jones. Originally listed at Grade II by English Heritage for its architectural and historical importance, its status was upgraded further to “Grade II*” on 18 March 2011.
