Marble stucco is an ancient technique that tends to imitate marble and is far cheaper.
The finish of this type of stucco can be of such high quality that it is indistinguishable from natural marble.
The interior of the church creates a continuously moving illusory effect thanks to some of its characteristic elements: the lateral arcades, the vault and the apse arcade seems to bring the gaze towards the altar.
With its countless stuccoes and frescoes, the vault creates the sensation of participating in a whirling motion where art and architecture interact.
Nothing seems motionless in this space and there is a continuous tension throughout.
