Giacomo della Porta, an eminent Italian architect and sculptor, was likely born in either Genoa or Porlezza, Italy, in the year fifteen thirty-two. His artistic journey began in his late twenties as a sculptor, drawing inspiration from the great Renaissance masters, including Michelangelo and Giacomo Barozzi da Vignola.
His architectural career took flight with his work on the Oratory of Santissimo Crocifisso in Rome, marking a significant transition from sculpture to architecture. In the year fifteen sixty-four, he was honored with the title of Architetto del Popolo Romano, or Architect of the Roman People, a position that allowed him to undertake some of his most distinguished commissions, both public and private.
Throughout his illustrious career, Della Porta was known for his unique approach to architecture, often taking on projects initiated by other architects. Rather than starting from scratch, he frequently made notable additions or modifications to existing works, showcasing his ability to blend his vision with that of his predecessors.
