The Tourist Information Office is on the Lisbon's trade square, and the popular plaza serves as the departure point for tour buses. Cruise ships also used the centrally located waterfront square as a shuttle bus drop off point. The Portuguese Palace used to be on the square before the great earthquake of 1755. Today, government offices ring the plaza.
