The Pavilion of Knowledge science centre is one of the extant gems of the 1998 World Expo. It was first built to focus on the mysteries of the oceans, but today it provides permanent exhibitions on chemistry, physics and other science subjects, mainly for the younger crowd.

The Roman Theatre was built between the first and second century AD, on behalf of Quinto Petronio Modesto from Trieste and it can hold about 6,000 spectators. The statues that adorned the theatre are now preserved in the Town Museum.

Visit the Sealife Centre and find out about the fascinating world of fish. This is a thrill for both adults and children. See everything from small seahorses and starfish to sharks and stingrays. Do not miss the shark tunnel and a pool where visitors are allowed to physically touch marine creatures.

The area where Expo 98 was held has been successfully transformed into a centre for exhibitions, leisure and culture. The extensive amount of building since the Expo almost overshadows pearls such as Siza Vieira’s Portugal pavilion and Santiago Calatrava’s adjacent Oriente Station. Green park spaces with public art link landmark contemporary buildings like the Camões Theatre and the Lisbon Oceanarium. Trendy waterfront restaurants, the glass-roofed Centro Vasco da Gama mall with shops and cinemas — everything you need for a fun weekend. Kid-friendly exhibits attract families to the Knowledge Pavilion, while the Telecabine Lisboa cable car offers sweeping views with a touch of adventure.
