Giovanni Battista Rezzonico (1 June 1740 – 23 February 1785) was an Italian cardinal of the Catholic Church.[1]
He was born in Venice, Italy. He was the nephew of Pope Clement XIII (Carlo della Torre di Rezzonico or Carlo Rezzonico Senior) (1602–1680). His brother Carlo (1724–1799) was also a cardinal and Camerlengo of the Sacred College of Cardinals from 1769 to 1799. On 10 September 1770, he was named a cardinal by Clement XIV and installed on 12 December 1770. He died as Cardinal-Deacon of San Nicola in Carcere. He participated in the 1774–1775 papal conclave.[2] [3]
In the 1760s, he engaged Giovanni Battista Piranesi to enhance the structure of Rome's Santa Maria del Priorato Church and its plaza, providing both with new decoration.[4]
