This is a picture vom the Porta S Giacomo in Bergamo during the blue hour. You have a beautiful view alongside the city wall and the upper parts of Bergamo (Citta Alta). From here one can see the bridge leading to the gate of San Giacomo. The city is nicely illuminated and in the background the mountains are still visible.
Bergamo during nighttime: in the foreground you can see Citta Alta, the upper city, which also is the old city of Bergamo. This picture was taken from San Vigilio looking down on the city. You can reach it with the funicular, which brings you up in a couple of minutes.
