The Lisbon Oceanarium, known locally as Oceanário de Lisboa, opened in 1998 as the centerpiece of the Expo ’98 world’s fair and has since grown into one of the largest indoor aquariums in Europe. Built on a pier in an artificial lagoon within Parque das Nações, the building was designed by architect Peter Chermayeff of Cambridge Seven Associates to evoke the silhouette of an aircraft carrier rising from the water.
At the heart of the aquarium sits a massive central tank holding roughly 5 million liters (about 1.3 million gallons) of seawater, surrounded by four smaller habitat tanks recreating the rocky coasts of the North Atlantic, the Antarctic coastline, Pacific kelp forests, and Indian Ocean coral reefs. The layout lets visitors view pelagic species swimming near the surface and bottom-dwellers below in the same central volume, while the outer galleries showcase region-specific ecosystems overhead and underfoot.

A World’s Fair Legacy
The Oceanarium was one of the signature attractions built for Expo ’98, the world’s fair Lisbon hosted to mark 500 years since Vasco da Gama’s voyage to India. Unlike many expo pavilions that were demolished afterward, the Oceanarium was designed as a permanent institution, and it has remained one of the most visited attractions in Portugal in the decades since, anchoring the redeveloped Parque das Nações waterfront district.
Habitats and Signature Residents
Beyond the central tank, the Oceanarium is known for species that are notoriously difficult to keep in captivity, including ocean sunfish, sea otters, and spider crabs. Its ground floor also hosts the “Forests Underwater” exhibit, a large-scale nature aquarium designed by Japanese aquascaping artist Takashi Amano, alongside roughly two dozen smaller thematic tanks exploring different marine ecosystems.
