Esther Williams, eat your heart out!
This pool still exists. Apparently it was closed in the summer of 2009 due to economic cutbacks. Up to 10 000 people a day were using it on a weekend day. By 2010 the other pool was also closed. Read more here.
I collect vintage postcards of swimming pools. I plan to post one a day as far as possible. If you know any of these places, especially the fate of the pool, I'd love to hear from you!
