Back in the day, Cais das Colunas—where the Tagus River meets the Praça do Comércio plaza—was the official entrance to Lisbon, used by heads of state and other prominent figures. Here, looking out on the water, you can see the April 25th Bridge and the monument to Christ the King. To your right is Ribeira das Naus, the waterfront promenade. Now, turn your back to the river and take in one of the most palatial squares in Europe, in which you'll find Lisbon's oldest café, Martinho da Arcada. In front of you, the Triumphal Arch of Rua Augusta leads to a beautiful pedestrian street.
