Chiesa di Santa Chiara

The church of Sant'Antonio Abate was originally a Gothic building dating from the 14th century, erected by Friar Ciotto degli Abbati. After the patriarch moved from the castle of Udine to the new palace, it became the patriarchal chapel. The façade was completed between 1731 and 1734 and in 1733 by Giorgio Massari, commissioned by Dionisio Dolfin. Now deconsecrated, the church is used as an auditorium and hosts exhibitions.

Also known as the Udine Cathedral, the cathedral of Santa Maria Annunziata is the main church of the city of Udine. It was constructed in the 13th century, but was consecrated in the 14th century. The church follows the latin cross formation plan and is built in a franciscan style. Inside are several important frescoes, stainglass windows, and altarpieces.

The Metropolitan Cathedral of the Martyrs Saints Hilary and Tatian dates from the 13th century. In 1471, the Chapel of St. Acacius, the best preserved part of the cathedral, was built. Between 1682 and 1702, the church underwent a radical Baroque renovation: Giulio Quaglio painted a series of frescoes that were lost during the First World War. In 1751, Gorizia became the seat of the archbishopric following the dismantling of the patriarchate. It was severely damaged during the First World War: it was returned to worship in 1928, as recalled by a plaque outside, in its present form.
