Church of St. Euphemia

The Euphrasian Basilica, now the cathedral of Poreč, was built in the 6th century on the site of an early Christian church at the time of Emperor Justinian I (483-565). The complex of the Euphrasian Basilica includes the Basilica, the Parish Church, the Sacristy, the Baptistery and Bell Tower, the Oratory of Mauro and the nearby Episcopal Palace. The mosaics of the interior and the facade of the church are among the best-preserved works of Byzantine art. In 1997, UNESCO declared the basilica a World Heritage Site.

The Serbian Orthodox community got permission to build an Eastern Orthodox church in 1788. The Church of St. Spyridon got its current form in 1834.

The Pula Cathedral was created by the extension of the previous religious buildings, present on the site since the 5th century. It was richly decorated with murals and mosaics on the floor, a very small part of which has been preserved today. The present classical facade was donated in 1712, at the time of Bishop Bottari, when extensive restoration work on the basilica and the Baroque bell tower began, which was completed in 1924. The free-standing bell tower was completed in 1707.
