Cathedral of St. Duje, or the cathedral of St. Duje (Dujama) is the main Roman Catholic temple in Split, where the relics of its patron are kept. It is located in the Diocletian's Palace - a famous architectural complex, inscribed on the UNESCO World Heritage List. Originally, the temple building was the mausoleum of Diocletian, which in the VIII century AD was rebuilt into a cathedral.
After numerous reconstructions, the cathedral is a mix of architectural styles - from Romanesque to Baroque. The great attraction is the treasury, which houses a rich collection of silver and gold liturgical vessels and antique prints. In the 13th century, the cathedral was equipped with an impressive, richly carved portal and a stone pulpit. The current main altar is much later - it dates from the 17th century.
According to the tradition of St. Dujam was a Christian martyr from the first century AD He taught in Roman Solon (now Solin) during the reign of Diocletian. He died on the orders of the emperor, together with several dozen fellow believers. Currently, the martyr and his persecutor rest in the same place.
