Sant'Antonio Abate is an ancient church in Pisa, Italy facing the Piazza Sant'Antonio. It was founded in 1341 with an adjacent convent. It was nearly destroyed after World War Two, and was rebuilt. The inferior façade, in two colors of marble, was the design product of Lupo, Giovanni di Gante, and Simone di Matteo of Siena. The vast 1989 mural of Tuttomondo by Keith Haring, was one of the last public works of the graffiti artist.
