River Trubia
The River Trubia is one of the most important tributaries of the River Nalón. It rises at the junction of the Ricabo and Lindes rivers, and flows 31.3 kilometres until it reaches the town of Trubia, where its waters merge with those of the Nalón.
The entire course is protected for its environmental value. The headwaters of the river are within the Las Ubiñas-La Mesa Natural Park, and the rest of its course and banks form the Río Trubia Special Area of Conservation (SAC). This area of almost 74 hectares preserves valuable riparian forests and protected oak groves and is a refuge for such emblematic species as the Atlantic salmon, otter and desman.
The toponym Trubia comes from trans-upia, which can be translated from Latin as "on the other side of the river". This makes sense considering its geographical location: from Oviedo, this river lies beyond the River Nalón, which would explain this curious name.
In addition to its ecological value, this river has a strong historical significance. In the 19th century, it became an economic engine for the area with the installation of the Royal Arms Factory of Trubia on its banks. After the attacks on the Navarrese factories during the war against France in the 18th century, a more sheltered location was sought for them, with access to essential resources such as wood, iron, coal and, of course, water.
