The Oceans Pavilion, a centerpiece of Lisbon’s Expo ’98, stands as a testament to innovative architectural design and marine conservation. Designed by Peter Chermayeff, the pavilion is strategically located in the Olivais Dock, symbolizing an island amidst the sea. This unique structure is characterized by its omnidirectional form, resembling a ship with masts and sails, and is oriented to capture light from all directions. The main building, set in the water, features a massive central tank representing the unity of the world’s oceans, surrounded by exhibits of the Atlantic, Pacific, Antarctic, and Indian coasts. Visitors can explore these environments across two levels, with the upper level offering views of coastal habitats and the lower level providing a glimpse into the ocean’s depths. The pavilion’s design integrates advanced mechanical systems to maintain optimal conditions for its diverse collection of marine life, which includes approximately 8,000 specimens across 250 species. A pedestrian bridge connects the main structure to a land-based building housing visitor amenities, ensuring efficient crowd circulation. The pavilion not only showcases the beauty and diversity of marine ecosystems but also emphasizes the importance of ocean conservation through multimedia exhibits and educational programs.
