Man has always ventured into the unknown. Almost five centuries ago, the Portuguese navigators started a new Era. Mare Clausum has the purpose of honoring all Portuguese navigators who, through their expeditions, brought a new world to the World. Expeditions that were marked by courage, persistence, ambition, and, of course, glory. Glory to have arrived where no one had arrived before. Glory to have written a new History. The History of the Portuguese Discoveries.
