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.

The Cudillero Tunnel (Túnel de Cudillero or Río Piñera Tunnel) is a fascinating, historic pedestrian tunnel from the late 19th century. It runs for about 300 meters through the mountain and connects the picturesque fishing harbor directly with the upper part of the village.

The small fishing village of Cudillero on the coast of Asturias, west of Avilés, is one of the most beautiful coastal towns on the Spanish north coast. Colorful houses climb the green hills, while fishing boats bob in the blue sea below. Sights in Cudillero include the picturesque old town, the harbor district, and the many viewpoints.
