- The major public square in Lisbon is called Praça do Comércio. It was constructed on the site of the former Royal Palace, which stood beside the river until being leveled by an earthquake in 1755.
- The Arco da Rua Augusta, often known as the “Rua Augusta Arch,” is the centerpiece of the square. It was constructed in 1873 to commemorate Lisbon’s restoration following the devastating earthquake.
