There was a discussion today with lots of callers on the Roger Phillips phone in regarding Liverpool's lost open air baths with people recalling Burlington st, Mansfield St, Bootle etc with side issues concerning other open water bathing such as the scaldies down by Tate & Lyle in the canal or up by the tar works in Litherland.
Of course New Brighton was mentioned and I also remember rock ferry.
There was also of course Cornwallis street salt water baths but this was enclosed. I notice there are also threads about Crosby baths and Garston baths already existing here.
Here are some from the port cities site.
