Church of St. Ignatius of Loyola, Gorizia

The Chapel of the Holy Spirit is Gorizia's oldest church, located in the old castle. Despite the castle being damaged during the First and Second World Wars, the chapel survived without serious damage. During the Second World War, the chapel was used to store amunition. It was restored in 1931 and reopened for worship in 1946.

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.

The original church was built in 1497. It was rebuilt between 1624 and 1637. the current neoclassical facade, designed by Giovanni Brisco, was built in 1898, when it gained the status of parish church. The First World War caused part of the roof to collapse. The church was restored in the 1920s.
