Creating a documentary based on all the churches in the territory of Rome would be an impossible operation. My intent therefore is to make known a small cross-section that, although in its small realization, wants to highlight the supreme art with which these churches adorn the territory of the eternal city. I will dwell on some examples depicting the harmony of marbles and stucco, on the polychrome of the ceilings, on the adoration of the icon, where the icon is intended as particular form of the presence of God, on the multiple expression of the artistic form that aims to adoration.
