The Praça do Comércio (Portuguese pronunciation: [ˈpɾasɐ du kuˈmɛɾsiu]; English: Commerce Square) is located in the city of Lisbon, Portugal. Situated near the Tagus river, the square is still commonly known as Terreiro do Paço ([tɨˈʁejɾu du ˈpasu]; English: Palace Square), because it was the location of the Paços da Ribeira (Royal Ribeira Palace) until it was destroyed by the great 1755 Lisbon Earthquake.
