Edifici del Semàfor

The building was erected in 1887 in order to regulate coastal marine traffic and prevent accidents. The watchmen who lived there would notify Montjuïc Castle of any incidents. They would also rescue the victims and salvage any shipwrecked vessels and their contents. The building was restored by the ACA (Catalan Water Agency) courtesy of the water company Aigües Ter Llobregat (ATLL), as territorial compensation for the installation of the metropolitan desalination plant. The Traffic Light is located amid wetland flora, with flooded marshes, reeds, seablite and marsh samphire, along with significant populations of esparto grass. The peacefulness of the unspoiled beach where it stands means that various species of birdlife feed there, including the Kentish plover (which also breeds here), the Audoin's gull and the osprey.
