Giulio Cesare Fontana

He trained in the studios headed by his father, his uncle Giovanni Fontana, his cousin Carlo Maderno, Matteo Castelli and Girolamo Rainaldi.

[1] In 1607, following his father's death, he became chief royal architect of the Kingdom, restoring Castel Nuovo and leading work on the Palazzo Reale.

That same year he took part in the competition to design the Royal Chapel of the Treasure of St. Januarius organised by the Deputazione della Real Cappella del Tesoro.

A commission in Rome judged the competition and the designs by father Grimaldi and Giovanni Cola di Franco were declared the winning entries.

Around the same time he designed the grain pits in Largo Mercatello (now Piazza Dante) in Naples and worked on the Regi Lagni.
