1. Praça do Comércio: Take in the Riverside Setting
Praça do Comércio opens onto the Tagus and puts you close to Baixa's restaurants and riverside walks. Its broad, central setting makes it a natural place to soak up the New Year atmosphere and look out across the water. Baixa and Chiado are handy areas to search for a place to stay, too. A city fireworks display and official viewing areas for 2026-2027 are still to be announced, so treat the square as a scenic riverside option rather than a guaranteed fireworks spot.
