Opened as a major icon of the world exhibition of 1998, under the theme “The Oceans – A Heritage for the Future”, the Lisbon Oceanarium perpetuates centuries of the symbiotic relationship between the city of Lisbon and the Oceans.

Considered by many times one of the best aquariums in the world, it combines the quality of its exhibitions and educational project, a unique architecture, guaranteeing to its visitors an unforgettable experience. A giant aquarium dedicated to the oceans and their conservation, which emphasizes the benefits of a harmonious relationship between man and nature.

The main building is surrounded by water. The idea is ‘ an island firmly standing in the middle of the ocean and an anchored ship, ready to set sail on a voyage of discovery’.

The Effisus Stopper solution – an innovative solution sealing penetrations, of any size or configuration, on flat roofs – has recently been used to seal penetrations points made in the roof of the main building.
