The church of Santa Trínita was founded by the Vallombrosians in the 11th century (when it was outside the city walls), and subsequently patronized by many of Florence's wealthiest families; as a result it was rebuilt many times. The current church was constructed in 1258–1280 at the site of the pre-existing 11th-century church. The nave and most of the chapels are from the fourteenth century and were completed between 1383 and 1405.

The big church is dark, even on bright days, and very wide with unusually wide aisles. A notable feature is the absence of columnar forms of any kind. The square piers greatly emphasize the effect of the flat termination of the choir.

The church has approximately 20 chapels, many with masterworks: it is home to the Sassetti Chapel, containing 15th-century frescoes by Domenico Ghirlandaio, and the Bartolini Salimbeni Chapel, with frescoes by Lorenzo Monaco.
