Besòs Mar is a station in the Barcelona Metro, in La Mina, an area of the Sant Martí district of Barcelona. It's served by L4. It was opened in 1982 as La Mina, but it was controversially renamed with the construction of the Barcelona Fòrum and revamping of the adjacent area into Besòs Mar, alluding to the proximity to the Mediterranean Sea and to the Besòs river in order to diminish the reference to the neighbourhood's name which had become infamous.
