The city was probably a Roman post station (Mansio Apicilia) on the Via Annia which connected Concordia to Aquileia.

The city is first mentioned in 1072, and became an important river port in the 12 and 13th centuries, especially known for salt trade, under the counts of Gorizia.

The trade declined in the late years of the Republic of Venice, and the city was acquired by the Austrian Empire with the Treaty of Campo Formio (1797).

The main attractions are the canvas portraying the Baptism of Jesus (1567) by Paolo Veronese and a wooden Crucifix (1566) by Andrea Fosco.

The choir has a Transfiguration (1591) by Marco Moro and the first altar on the left has a Holy Family with Saints by Giovan Battista Grassi (1568).
