Santissima Trinita degli Spagnoli
The 18th century convent church of Santissima Trinità degli Spagnoli (Most Holy Trinity of the Spaniards) was built for the Spanish branch of the Ordo Sanctissimae Trinitatis et Captivorum (Order of the Most Holy Trinity and of the Captives), better known simply as the Trinitarians.

The Trinitarians were founded in 1198 by St John of Matha (1160-1213) and St Felix of Valois (1127-1212). Their mission was to raise the money to pay the ransoms of Christians taken prisoner by Muslim pirates and slave-raiders. This explains the presence of the striking sculpture of the Angel With Two Prisoners by Pietro Pacilli (1720-73), above the entrance.
