The construction of the dam on the Serpis Historical milestone · Beniarrés, El Comtat, Alicante Image of Beniarrés, not of the place itself. The dam on the Serpis was completed in 1958 to check floods and irrigate the fields of the Safor. Its backwater flooded terraces and mills at the bottom of the valley and forced the rerouting of tracks and paths that linked the riverside villages. 1958 Photo: Joanbanjo (CC BY-SA 3.0) What to see and do in Beniarrés
