Torrievieja has a long tradition with the sea, and in 1803 the administration of the Royal Saltworks was transferred to Torrevieja from La Mata. The purpose of the museum is to show how the town grew through its link with the sea and the production of salt. The museum is divided into themes, including undersea archaeology, coastal navigation, the town`s fishing fleet, Spanish navy, carpentry, the making of sails and saltworks.
