Submarino S-61 clase Delfín, Military submarine museum in Torrevieja, Spain
The Submarino S-61 Delfín is a military submarine now serving as a floating museum in Torrevieja's harbor, displaying the design of a Spanish naval vessel from the 1970s. Inside, visitors can see control rooms, crew sleeping quarters, and mechanical systems that kept the boat operational during its decades of service.
The submarine was built in 1972 and entered service with the Spanish Navy in 1973, patrolling the Mediterranean and performing coastal defense duties. After three decades of operation, it was retired and brought to Torrevieja in 2010 where it has remained as a permanent exhibition.
The ship reveals how the Spanish Navy watched over Mediterranean waters and protected coastal trade routes that shaped the region's identity. Visitors today walk through the same passages where crew members worked daily, seeing firsthand the demands of underwater service.
The vessel is located in the harbor and accessed by stairs and ladders, so wear comfortable shoes for navigating the narrow passages. The confined spaces and vertical movement make it important to check accessibility before visiting if you have mobility concerns.
The boat retained its original torpedo tubes and firing systems, which visitors can see to understand how the vessel would have engaged in Cold War conflicts. It remains rare to step inside a former warship with its weapons systems fully preserved and on display.
