context_page_description: Entrambasaguas is a small municipality located in the autonomous community of Cantabria, Spain, 25 km south of the Bay of Santander. It is moderately mountainous, and the origin of the Aguanaz River, which once drove 23 watermills and merges with the Miera River. Limestone caves with Paleolithic rock art and burial sites from the Bronze Age exist. Iron was mined here from prehistoric times, used in the Royal Artillery Factory of La Cavada, which supplied the Armada, and eventually brought some wealth during the Renaissance. First mentioned in 1210, this rural area of Green Spain consists of six towns an area of 43.2 square km, totaling about 5,000 inhabitants as of 2015, having nearly doubled since 2005.
context_section_description: Entrambasaguas lies in the southern arc of the Bay of Santander and has a smooth topography. Two rivers, the Miera River and its tributary the Aguanaz, flow through its traditionally rural landscape of moderately high mountains and patches of woodland and cow pasture. Mount Vizmaya forms the gentle relief of Entrambasaguas; it is a 249 meter high rugged limestone massif with various caves and the vestiges of a Cantabrian castle serving as a vantage point at its peak. 
  There are remains of 19th century iron mining and lime kilns from mining of limestone.
  The Miera is one of the main rivers of Cantabria and has been declared a 'site of community importance' for being a natural area that helps preserve habitats and endangered species. The Miera has fishing reserves and originates in the portillo de lunada (lit.: halfmoon passage). After passing through San Roque de Riomiera it disappears from the surface, embedded in rough limestone slopes up to the town of Liérganes, where it resurfaces again. After passing through La Cavada and the landscape of the Trasmiera, it ends its course in the ría de Cubas, leading to the Bay of Santander. The Aguanaz is also born by a karstic spring located in the district of San Antonio, which after crossing Entrambasaguas and Hoznayo passes through the natural bridge of the Fuente del Francés joining the Miera River in Villaverde de Pontones.
