Santa Trinita ("Holy Trinity") is a church in central Florence. It is the mother church of the Vallumbrosan Order of monks, founded in 1092 by a Florentine nobleman. Nearby is the Ponte Santa Trinita over the river Arno.
The church is famous for its Sassetti Chapel, containing notable frescoes by Domenico Ghirlandaio, ranked amongst 15th century painting's masterworks.
Even though the Italian word for "trinity" is trinità, with an accent indicating stress on the last vowel, the Florentine pronunciation puts the stress on the first vowel, and the name is therefore written without an accent; sometimes, it is accented as trìnita to indicate the unusual pronunciation.
The current church was constructed in 1258–1280 over a pre-existing 11th century church. Multiple reconstructions occurred thereafter. The Mannerist façade (1593–1594) was designed by Bernardo Buontalenti. The relief over the central door of the Trinity was sculpted by Pietro Bernini and Giovanni Battista Caccini. The 17th century wooden doors were carved to recall saints of the Vallumbrosan order. The Column of Justice in the Piazza outside, originates from the Baths of Caracalla, and was a gift to Cosimo I de' Medici by Pope Pius IV. It was used in 1565 to commemorate the Battle of Montemurlo.
