Thanks everyone, it is indeed a beautiful city, especially with nice autumn light.
Photos #2 and #3 are taken form the Senhora do Monte Miradouro, the highest belvedere that overlooks downtown, the castle, and the river.
I am not sure if later on there are more dazzling lights in downtown, I suspect not. At the time photo #3 was taken, around sunset, the lights were coming on in some of the houses and streets. The scene was recorded as is.
