The Rua Augusta Arch, located at the entrance to Praça do Comércio, is one of Lisbon's most iconic landmarks and a symbol of the city's reconstruction after the 1755 earthquake.

Visitors can take a lift and stairs to a rooftop viewpoint offering 360° views over Baixa and the Tagus River, along with a small exhibition about the monument's history. It's a popular photo spot, especially at sunset when the surrounding streets are lively and filled with street performers.

Entry is included with the Lisboa Card, making it a convenient stop while exploring central Lisbon.
