We know of pools on Portugal’s Mainland and its islands that fit our definition of an ocean pool, but as yet we have little information about their history or their heritage significance.

Ocean pools on Madeira
Madeira has many seapools.
Porto Moniz, Madeira
A set of magnificent pay-to-swim saltwater pools with fixed summer and winter opening hours are located in the village of Porto Moniz, on the island of Madeira in the Atlantic Ocean west of the Mediterranean Sea. Kate Rew rates those pools among Europe’s top 10 seawater swimming pools.

The Seixal pools
There is a sublime, Olympic-length pool under a natural rock arch at the bottom of a steep road known as Frente de Mar do Seixal. Next to that is another pool see image below.(Thanks to our member, Sheridan Hopkins, for this information and her images.)
