Not many roman people know the secrets of this church, that is visited more by the (few, compared to the crowds of the other roman attractions) tourists that have chosen this place among the thousands of things to see in Rome.
The church is one of the masterpieces of baroque in Rome, and is located in the center, close to via del Corso. What makes it really unique is a play of perspective created by the paintings of father Andrea Pozzo. To enjoy it at best i suggest to follow a simple itinerary. From the entrance proceed straight a stop where geometries in the pavement form a circle. Place there and look at the top. You’ll see an extraordinary painting, depicting the epic of jesuites (the church is dedicated to the father of the Jesuit order). The author made the perspective so that it seems the ceiling is twice as tall as it is actually, and managed to create straight columns out of a curved ceiling.
Proceed towards the end of the church and top where a small circle is placed on the floor. This is another place from where to look upwards. Admire the dome and it’s perspective. Because, proceeding on, you’ll discover that… there is no dome, it’s just painted!!!!
