What to do in Santo Andre

Officially named Praça Dom Pedro IV, this centrally located square is much more commonly known simply as Rossio. Come here at any time of the day to find the square abuzz, as people gather to socialize at cafés around the square’s edge.

In the early 16th Century, this four-storey tower was built on basaltic rocks found by the Tagus River, in close proximity to the riverbank, with the intention of supplementing the existing fortification defences along the sea approach to Lisbon.

The Lisbon Oceanarium is the largest indoor aquarium in Europe and houses more than 8,000 fish, birds, mammals and invertebrates. Bring the family to be entertained while learning about conservation and ocean habitats around the world.

The Castle of São Jorge is a huge medieval structure that overlooks the city. Take a guided tour to learn about Lisbon’s past and enjoy views across the capital from the castle’s grounds.

Commerce Square, or the Praça do Comércio, is a meeting place for locals and a great spot to bask in the sun along the riverfront. This was the site of the royal palace for many centuries, until the Great Earthquake of 1755. The palace was remodeled into an elaborate stone monument that marks the point of entry to the city. Today the square offers many places to sit and relax in between visits to the surrounding sites of the central Baixa district.
