A Hellish Look
It is quite common these days to see images of various kinds using the facade of a building as a screen. In the case of government or state buildings, a flag appears out of nowhere after dusk.
The overall effect is quite spectacular, especially in Italy where the palaces of power are beautiful works of art. However, when photographed with a narrow field of view, the result can be disturbing, as in this case, where the building looks more like some sort of hell embassy.
It wouldn’t be strange, though: doesn’t the Pope live on the other side of the Tevere River?
