Church of St. Mavra

The Cathedral of the Assumption of Mary is a Romanesque church dating from the 11th century. Hardly anything is known about the cathedral before the year 1000, although in Koper, with interruptions, bishops have been enthroned since 520. The oldest mention of the Romanesque Church of Mary in Koper dates back to the end of the 11th century. The church houses the relics of St. Nazarius and St. Alexander.

The minority monastery of Piran has existed since the 14th century when the first church was built on top of the hill in 1301. From 1954 to 1990, the complex was nationalized. The church took over the monastery in 1996, after the denationalization. The cloister is preceded by a half-arched portal decorated with richly carved columns, bearing an architrave with an inscription and coat of arms.

The church of St. Jurija was built in the Venetian Renaissance style between 1595 and 1637. The existence of the first Christian church from the 6th to the 7th century is known from archaeological research. Subsequently, historical sources confirm the existence of a parish in the 10th century, as evidenced by fragments of an old church in a lapidary dating from the 10th to the 12th century. The former Aquilian-style church basilica was replaced by a Gothic church with three naves, consecrated in 1344.
