BesArt. The River Museum is a new proposal for the largest open-air urban art museum in Europe, located on the walls of the Besòs River. There will be a total of eight kilometres of river frontage (four on each side), but the aim of the project's promoters is for the museum to occupy the entire length of the river, a total of about 18 kilometres.
