Cathedral of Saints Ilario and Taziano

The Basilica of Mary of the Assumption is one of the most important pilgrimage sites in Slovenia. The basilica is the branch church of the parish of Solkan, but it also serves as the church of the Franciscan monastery of Sveta Gora. The church was first built in the first half of the 16th century after a pre-existing shrine of Mary was demolished by the Turks in 1496. Destroyed during the First World War, the present basilica was erected in its place between 1920 and 1932.

Monfalcone Cathedral was built between 1926 and 1929 on top of an old 18th-century church, traces of which can be seen behind the present cathedral. This church was itself the restoration or reconstruction of an ancient church of medieval origin. During the hostilities of the First World War, the bell tower collapsed on the building, eventually destroying the church. At the end of the war, the only remaining place of worship had to be rebuilt, hence the construction of the present neo-Romanesque building in the 1920s.

The Sanctuary of the Holy Virgin Marcelliana was built between 1841 and 1844 on an old medieval church. In 1939, the Franciscan monastery was built next to the church. After the Second World War, due to the increase in the population of the village of Panzano, the parish of the Madonna Marcelliana was created.
