'Puerta Beta' was based on the site specific performance ‘Fuera de la fábrica Beta’, a collective creation directed by Nilo Gallego, in which the public, located inside an abandoned factory, a symbol of the industrial decline of the area, could observe the busy transport routes that connect the outside with the centre of the city of Bilbao, through a game between the everyday, chance and a series of interventions in which the residents of the Zorrozaurre neighbourhood participated.
