About Besòs Mar
Located in Barcelona’s Sant Martí district, Besòs Mar reflects the city’s urban evolution: from a Roman agricultural plain and industrial hub to a modern community focused on environmental renewal. Its industrial legacy, contemporary urban planning and ecological initiatives offer a different perspective on Barcelona from its better-known monuments.
The neighborhood has a vibrant multicultural community, green spaces, urban beaches, local festivals and accessible transport. Highlights include the Besòs Mar Biodiversity Refuge, Parc de la Desembocadura del Besòs, Parc del Fòrum, Museu Blau and nearby beaches such as Platja del Llevant. Besòs Mar offers a way to explore Barcelona’s social and environmental regeneration, with connections by metro (L2 and L4), the Trambesòs tram and several bus lines (Explore Besòs Mar, Besòs Mar Biodiversity Refuge, Barcelona Transportation Guide).
History and urban transformation
Fertile land along the Besòs River supported agriculture for ancient Barcelona in Roman times. The area retained a rural character through the Middle Ages, when it was centered around the Romanesque chapel of Saint Martin of Tours. The industrial revolution brought textiles and heavy industry, transforming Besòs Mar into a working-class area shaped by rapid urbanization and a multicultural workforce.
The 1992 Olympics and subsequent urban renewal programs helped drive the neighborhood’s transformation. The Olympic Village, new parks and the Diagonal Mar development reimagined former industrial spaces as public areas. The area has also faced economic challenges and the legacy of industrial decline, while community efforts continue to work on social cohesion and safety.
Recent projects have focused on upgrading housing, improving energy efficiency and involving residents in community planning. Ecological restoration has turned the once-polluted Besòs River into a green corridor supporting biodiversity and climate resilience. The Besòs Mar Biodiversity Refuge is part of this wider effort.
