Praça do Comércio
The king's palace stood here until 1 November 1755, when an earthquake, tsunami, and fire erased it — every stone you see is the deliberate replacement.

At 175 by 175 metres, this Tagus-facing plaza was rebuilt from scratch after the 1755 disaster under the Marquis of Pombal's reconstruction of Baixa. For the next two centuries the surrounding arcades housed the Ministries of Finance, Agriculture, Maritime Affairs, and Colonies, making the square a literal metonym for Portuguese central government. Classified a National Monument in 1910, it still holds the Supreme Court.
What to look for
- The open south face pointing directly onto the Tagus river — orientation to the water was a deliberate choice of the post-earthquake rebuild
- The arcaded ministry buildings enclosing three sides, several of which still function as government offices today
- The metro entrance: Terreiro do Paço station runs directly beneath the square
Terreiro do Paço metro station sits under the plaza — exit straight into the square with no street navigation needed.
