Just at this point the Royal Palace was located, which was totally destroyed in 1755 by the terrible earthquake, sutnami and fire generated; After all this, the Marquis of Pombal decided to rebuild it in a „U“ shape, with three large porticoed buildings that today house some government agencies, the main Lisbon tourist office and some restaurants and cafes. Today the square also acts as a nerve center for transportation in the city, so you will see a large number of tourist buses and trams go by.
It is recommended to get to the banks of the river, where we can still see the staircase used by the ancient monarchs to disembark on their arrival in the city.
To get a good panoramic view of the Commerce Square, it is best to go up to the viewpoint of the Rua Augusta Arch, recently opened and with a spectacular terrace.
