This gate was built in the 14th Century, which indicates that it was originally part of the city's defensive works. In the 19th Century, the center arch was widened after being damaged in by an explosion. Today, the gate closes off this important street while still permitting a glimpse of what lies beyond. This street is still carfree today, and the trams have been replace by an underground metro.
It appears that the photographer crudely retouched the wires out of the sky, although the two black lines might be scratches on the original negative. Notice how distracting they are; they will have been removed since then.
Notice also that the flagpoles cry out for flags, and that on carfree streets, pedestrians make use of the full width of the street. Finally, observe the rooftop decorations.
