Follow your guide through the darkened corridors of the historical mansion. Now you come to a halt before an old door.

You hear the key rasping in the keyhole, the hinges creaking, and then — light.

Bright daylight in your eyes. You are on a balcony, as if suspended in mid-air; and right in front is the imposing marble colonnade of the Roman Forum.

Twenty centuries of history look at you. And from here you will appreciate them from a whole different perspective, at your leisure, and undisturbed by the crowds that gather below.
