Thanks architectural decisions and perspective drawing achieved an illusory effect of the extraordinary depth of the temple. Large windows are well-lit interior space, filled it with light and allow the visitor is in the details of the entrance to consider painting the interior.
The main facade of the church is elegant in design and is very dynamic in its construction. The composition of the facade is visible to the strict symmetry. Doorway, window, niche window of a drum (all in the singular) are located on one central axis. Acceptance of this reinforces the impression of upward aspiration of the entire structure.
This church is absolutely unique. As a fine example of late Baroque architecture with elements of classicism, in its internal structure, he has only one analog in the world. This so-called, Scala Santa - Holy Stairs.
