Sant'Antonio Abate, Romanesque church in Piazza Sant'Antonio, Pisa, Italy.

Sant'Antonio Abate is a Romanesque church on Piazza Sant'Antonio, featuring a facade decorated with two-colored marble. Architects Lupo, Giovanni di Gante, and Simone di Matteo from Siena designed the building with characteristic Romanesque elements.

The church was founded in 1341 and originally built with an attached convent. After suffering severe damage during World War II, it underwent substantial reconstruction and repair.

The church is dedicated to Saint Anthony Abbot, and the square in front of it, Piazza Sant'Antonio, takes the same name. The convent founded with it in 1341 stood beside the church until World War II. On the convent wall along Via Zandonai, Keith Haring painted Tuttomondo in 1989, his last public work before his death from AIDS in 1990.

Visitors can attend mass services on weekdays and weekends at scheduled times throughout the day. It is worth checking specific service times in advance, as these may vary by season or for special religious occasions.

The rear wall of the attached convent facing Via Zandonai displays a large mural created by Keith Haring in 1989. This work stands as one of the final public pieces the renowned American artist completed during his lifetime.
