Sant'Agata, Medieval church in San Ambrogio district, Florence, Italy

Sant'Agata is a church on Via San Gallo in Florence, built in 1592 at the expense of Lorenzo Pucci and designed by painter Alessandro Allori. Its mannerist facade bears a worn Pucci coat of arms in pietra bigia, and the wooden portal doors show the pincers and breasts of Saint Agatha's martyrdom. Inside, a raised nuns' choir sits above the nave, and the presbytery holds Allori's Wedding at Cana (1592–1600) in a monumental wooden frame.

The monastery was founded around 1185 and housed twelve female monastic orders over time, including the nuns of Sant'Agata from 1211 to 1286 and Camaldolese nuns from Bibbiena after the Battle of Campaldino in 1289. The church was built in 1592 at the expense of Lorenzo Pucci, with Alessandro Allori as architect. The monastery was suppressed in 1808, restored after 1814, and from 1861 the complex served as a military hospital of the Kingdom of Italy, while the church remained with the diocese.

The name comes from Saint Agatha, whose martyrdom is shown in the tenaglie con i seni carved on the wooden portal doors, probably designed by Allori. Inside, the raised nuns' choir sits above the nave facing the altar, a rare arrangement still visible today.

The church is on Via San Gallo, while the former monastery complex now serves as the Military Hospital of Sant'Agata, entered from Via Cavour. The Diocese of Florence opens the church only for special events, so visits are not possible on ordinary days.

The wooden door leaves, probably designed by Alessandro Allori, carry tongs gripping breasts, the instrument of Saint Agatha's martyrdom, beside shields with the Pucci coat of arms. The worn Pucci emblem above them was cut in pietra bigia, a stone that erodes faster than the pietraforte usual in Florence, which is why its inscription is now almost rubbed away.
