In the 1930s, there were countless lidos in use across the UK. These beautiful outdoor pools brought a dash of Hollywood glamour to British summer days.
With slick architecture, carefully curated cafes and the birth of the risqué bathing suit, they were a place for Bright Young Things to see and be seen.
The rise in foreign holidays and squeezed council budgets means a lot of these places have long since fallen into disrepair.
But the past 10 years has sparked a revival for some, with community projects restoring beloved bathing spots of years gone by to their former Art Deco glory.
Here are 12 gorgeous al fresco pools to throw some shapes in this summer. After a hot day slaving in the office, there's no better place to be...
