Giovanni Carlo Galli-Bibiena (August 11, 1717 - November 20, 1760), was an Italian architect and designer.
He was the son of Francesco Galli Bibiena and a member of the Galli da Bibiena family of artists. He was a member of the Accademia Clementina in Bologna.[1]
In Bologna, he decorated the staircase of Palazzo Savini and the chapel Cappella di San Antonio in San Bartolommeo di Porta Ravegnana. Giovanni Carlo also designed a decorative scheme for the high altar of San Petronio, Bologna, for the Bolognese Pope Benedict XIV.[1] In 1752, he was summoned by Joseph I of Portugal, to Lisbon, where he designed the Ópera do Tejo adjoining the royal palace, but the opera house was destroyed seven months after completion by the 1755 earthquake. Giovanni Carlo Galli-Bibiena died in Lisbon.[1]
