 From 1565 until 1569 the architect Galeazzo Alessi played a decisive role in the renovation work, as did the Perugian architect Domenico Alfiano, and Valsesians Giovanni d’Enrico and Bartolomeo Ravelli.The sculptors, Tabacchetti, Giovanni D’Enrico, and painters like il Morazzone, Tanzio, Rocca, the Gherardini brothers, and the Gianoli brothers worked in the same artistic vein established by Gaudenzio Ferrari.However, Morazzone and the d’Enrico brothers, Giovanni and Tanzio, helped concretize the "gran teatro montano".
