We hope that these retro reminders of pools down the years bring back lots of happy memories. Some are no longer with us but we are sure the memories remain of these venues.
So whether it was Seaton or Brierton, or the open air pool on the Headland, we have photos of them all.
Dive in and take a look, and then get in touch with your own memories.
