Opened in 1998, the Oceanário was the centerpiece of the XXth Century's last World Fair, themed "The Oceans, a Heritage for the Future", and eternally binds Lisbon to the Oceans.MissionThe Oceanário’s mission is to promote knowledge of the oceans and bring up the public about the duty of protecting natural heritage, through changing their daily habits.While walking through impressive and unforgettable exhibits, visitors are encouraged to learn fascinating things about the oceans and, more importantly, how to make decisions in their daily lives that actively promote the conservation of nature.
