Sant'Antonio Abate, Former church in Piazza Patriarcato, Udine, Italy

Sant'Antonio Abate is a former church at the northeast corner of Piazza del Patriarcato. Its white stone facade, completed in 1731–1734 by Giorgio Massari, has a triangular pediment topped by a statue of Saint Anthony Abbot, flanked by Saints Hermagoras and Fortunatus. Four pilasters frame an arched doorway with a circular window above, and statues of the four evangelists stand before a low balustrade.

The Gothic building was erected in the 14th century by fra' Ciotto Ciotto degli Abbati, prior in Venice of the Order of Hospitallers of Vienne, and consecrated by Patriarch Nicolò di Lussemburgo in 1354. After the patriarch moved from Udine castle to the new palace it became the patriarchal chapel. Its bare facade was completed between 1731 and 1734 by Giorgio Massari for Patriarch Dionisio Dolfin.

The church became the patriarchal chapel after the patriarch moved from Udine castle to the new palace, and it holds the tombs of four of the last patriarchs of Aquileia: the funeral monument of Francesco Barbaro and Ermolao II Barbaro on the right wall, and the floor slabs of Dionisio and Daniele Dolfin. The facade statues of Hermagoras and Fortunatus in bishop's robes recall the origins of the Aquileia diocese.

The building sits centrally on Piazza Patriarcato and is easily reached on foot. The facade is clearly visible from the square, making it convenient to view from outside even if interior access is limited.

The pediment carries the Dolfin patriarchs' coat of arms, and the statues crowning it are Saint Anthony Abbot flanked by the proto-martyrs Hermagoras and Fortunatus in bishop's robes, carved by Antonio Gai to recall the origins of the diocese of Aquileia.
