Banyuls-sur-Mer is a commune in the Pyrénées-Orientales department in southern France.
Banyuls-sur-Mer is neighbored by Cerbère, Port-Vendres, Argelès-sur-Mer and Collioure. The region is known for its wines, such as the sweet wine Banyuls. An aquatic museum with aquarium is located in the town. The foothills of Pyrenees, the Monts Albères, run into the Mediterranean Sea in Banyuls-sur-Mer, creating a steep cliff line.
Banyuls-sur-Mer was first mentioned in 981 as Balneum or Balneola. In 1074, the town starts being called Bannils de Maritimo in order to distinguish it from Banyuls-dels-Aspres, which lies 20 km (12 mi) away. In 1197, the town is mentioned as Banullis de Maredine and in 1674. In Catalan, it has been called Banyuls de la Marenda, since the 19th century.
The name Banyuls indicates the presence of a pond. In fact, a pond did exist in Banyuls-sur-Mer until the creek Vallauria was drained in 1872. The term Marenda in Catalan or sur Mer in French merely indicates the proximity to the coast.
