St. Angnes Church is a Baroque building with magnificent and solemn effect. The walls are trimmed into concave arcs, and the upper part of the building is slightly extended.
St. Eugenis Church is in a golden area, that is, in the center of Navona Square. It can not be photographed in the church. Apart from the beautiful marble decorations common in Baroque churches, it can be said that it is one of the most impressive domes we have seen in Rome.
