Why go
This is the clearest place to understand how Lisbon reoriented itself after the 1755 earthquake destroyed the riverside royal palace. Eugénio dos Santos replaced it with a disciplined civic square open to the water, linking government and commerce to the rebuilt street grid behind it.
What to look for
- The symmetrical yellow buildings form a U that remains open toward the Tagus.
- Ground-floor arcades run beneath the long façades.
- The equestrian statue of José I anchors the broad center of the square.
Useful to know
- Approach through Baixa and finish at the river edge so the square's open side reveals itself gradually.
- The center is exposed to sun and wind; use the arcades when conditions are uncomfortable.
- Continue north through Rua Augusta to compare the square's scale with Baixa's regular blocks.
