Embalse de Mansilla

The Mansilla Reservoir is a large mountain reservoir linked to the Najerilla River, at the head of the Sistema Ibérico in La Rioja. Although the resource card places it in Viniegra de Abajo as a place that can be visited, the reservoir extends between Mansilla de la Sierra and Villavelayo and has a capacity of 68 hm³ and an approximate surface area of 246 hectares. It is, therefore, an artificial landscape with a strong natural presence, integrated in an environment of high mountains and mountain valleys. The most interesting thing for the visitor is the combination of water, relief and historical memory. From its banks there are wide views of the valley and the mountains, and in periods of low water, the remains of the old village of Mansilla de la Sierra, partially hidden under the reservoir, can be seen. This image, together with the mountain environment, explains its attractiveness as a place for walking and contemplation. The area is important for its landscape value and its functional role in the Ebro basin. The reservoir was built for irrigation, hydroelectric production and supply, making it a key infrastructure as well as a visual landmark of the territory. Its environment is linked to the mountainous nature of Urbión, with mountain and riverside ecosystems that reinforce its interest for a quiet and respectful visit.
