Castillo de San Martín

Highlight • Castle

The Castillo de San Martín, in the council of Soto del Barco, is located on the right bank of the river Nalón, on a pronounced bend from which the channel opens towards the estuary of San Esteban de Pravia. Its location, on a promontory barely 40 m high, provides it with an excellent visual domain over the mouth of the most important river artery in the region and justifies its long history as a fortification.
The current castle was built by Alfonso III on the remains of a previous settlement, in order to protect the coast and the estuary from Norman incursions.

Santa María del Mar Beach

Highlight • Beach

A golden cove in the heart of the tourist resort
The beach of Santa Maria del Mar, in the municipality of Castrillón, is a well-equipped urban cove that has a high occupancy rate. Just 300 meters long, it opens at the mouth of the Ferrera River.
Close to two campsites, it is bordered by the village of Santa Maria del Mar. Note an islet on its right, La Ladrona (the thief), whose legend has it that it was inhabited by a giant squid.
