Trieste Cathedral

The Trieste Cathedral is a Roman Catholic church dedicated to Saint Justus. It serves as the seat of the Diocese of Trieste. Visitors go here to see the religious architecture and the historical center of the city's ecclesiastical administration.

Getting There

The cathedral is located within the historic center of Trieste. It is accessible by foot from the main city squares and central pedestrian zones, typically taking only a few minutes to reach depending on your starting point.
