This square doesn't have a name. I am calling it by the name of the street it is in. It is actually a dead end of that street. It is still a square or largo by Lisbon standards. Even the church located here is not having name, it is called church at Rua Chagas, and very unusual but it looks like it is not in use.

Nice quiet place with one bench, with a view, of course occupied on the lovely sunny day. View is over, so common in Lisbon, street up and down the steep hill. This is one of three parallel very similar street along Rua Chagas. Value of spaces like this is often overlooked but in my opinion they are very significant for the health of urban life.
