We are now in "Comercio" Square, in front of the Tejo (Tagus) River (at our back). This square is one of the centers of the town.
Lisbon has three major "Bairros" (=neighborhoods): the Cidade Baixa (low district), the Bairro Alto (high district) and the Alfama (the oldest district).
The Comercio square sits in downtown Lisbon, the Cidade Baixa, a grid of small streets in the valley.
We’ll walk under the arch you’re seeing ...
