Corrales de Rota Natural Monument
These are small walls in the intertidal zone close to the beach at Rota, which cover 110ha and are exposed at low tide. They have been used for collecting shellfish and fish since Roman times and continued to be in use until the 1950s. Although under threat through illegal fishing, these are still some of the best preserved of their kind. The small walls allow the sea to enter the area behind at high tide, but they trap the fish when the tide recedes so that they can be easily collected.
They are of great ecological interest as they are home to a wide variety of flora and fauna that thrive on rocky or muddy shores. These include different types of seaweed, fish and molluscs. In turn, these attract many seabirds and waders, so it is also a good spot for birdwatching.
