The channelled Zapardiel and the río Viejo Nature · Salvador de Zapardiel, Tierra de Medina, Valladolid Image of Salvador de Zapardiel, not of the place itself. After the flood of 1860 the channel was canalised from 1867 and the old meander was left as the río Viejo. The whole, with the Morteros stream, is protected as a ZEPA and ZEC and preserves groves of white poplar. Photo: Rodelar (CC BY-SA 4.0) What to see and do in Salvador de Zapardiel
