The castle of Sant Carles and the lighthouse of Portopí were the stars of a new guided tour last Saturday to discover the historical and maritime heritage of the port of Palma. The activity is part of the initiative The secret heritage of the ports of the Balearic Islands, promoted by the newspaper ARA Balears with the collaboration of the Port Authority of the Balearic Islands and guided by Fita a Fita, which proposes bringing some of the most unique and unknown spaces of the Archipelago's ports closer to the public.
