Hotels near Lisbon Oceanarium

The Lisbon Oceanarium (Oceanário de Lisboa) was built for Expo '98 and remains one of the largest indoor aquariums in Europe. Designed by American architect Peter Chermayeff, the building sits in the middle of an artificial lagoon in Parque das Nações and holds roughly 8,000 marine creatures across 500 species. The central tank - visible from every floor - holds 5 million litres of seawater and is home to sunfish, sharks, rays, and a giant grouper that has become an unofficial mascot.

Four smaller habitats recreate the ecosystems of the North Atlantic, Antarctic, temperate Pacific, and tropical Indian Ocean, complete with penguins, sea otters, and a kelp forest that sways with artificial currents. The Oceanarium rotates temporary exhibitions - previous shows have explored deep-sea creatures and bioluminescence. Adult tickets cost €25 (€15 for children aged 3-12, free under 3). Opening hours are daily from 10:00 to 19:00 (extended to 20:00 in summer). Timed-entry tickets purchased online are strongly recommended.

Pro Tip: Visit on a weekday afternoon - school groups dominate weekday mornings and families fill weekends. The Parque das Nações area around the Oceanarium has a riverside promenade, the Vasco da Gama shopping centre, and a cable car running along the waterfront, so the trip easily fills half a day.
