Lidos & outdoor pools

Frequently asked questions

How many lidos & outdoor pools are in this guide?

We currently list 75 lidos & outdoor pools across the United Kingdom — every entry sourced from Wikipedia, Wikidata or OpenStreetMap and validated against our schema.

Are these places free to visit?

Many places in the guide are free to enter — almost every national museum, every public park and garden, every parish church and cathedral. Castles, historic houses and theme parks usually charge admission; National Trust and English Heritage members visit those properties free.

Where does the data come from?

Every entry is built from open data: OpenStreetMap (locations, tags, opening hours), Wikipedia (descriptions), Wikidata (structured facts and operator information), Wikimedia Commons (images), ONS open data (population). The site never makes runtime API calls — everything is fetched at build time and committed.

How often is this updated?

A weekly automated job re-fetches the upstream sources and rebuilds the site. Manual editorial corrections are applied as overlays on top of the open data.
