Giovan Battista Cavagna

Giovanni Battista Cavagna, also known as Cavagni or Gavagni (c. 1545–1613) was an Italian architect, engineer, and painter, active mainly in Naples, but also in Rome and the Marches of Italy.

In these years, he criticised his rival, Domenico Fontana, a later arrival to Naples, of selecting a poor site for construction the Royal Palace.

In 1610, he was active in Ascoli Piceno, and provided designs for the Oratorian church of San Pietro in Valle in the town of Fano in the Marche.

The ancient church of Santa Caterina ... was renovated by the Roman architect Giovanni Battista Cavagna between 1608 and 1613 (the year of his death).

Cavagna was closely connected with Oratorian circles and was the architect of the church San Pietro Valle in Fano, and of the Santa Casa in Loreto."
