The Cathedral of Saint Domnius in Split, Croatia, stands as the oldest Catholic cathedral in continuous use in its original structure, consecrated at the turn of the seventh century AD. The building originated as the Mausoleum of Diocletian, erected in AD 305 within the UNESCO World Heritage Site of Diocletian's Palace, and represents a remarkable fusion of ancient Roman and pre-Romanesque architecture. The complex comprises a church, strictly dedicated to the Virgin Mary, and a bell tower dedicated to Saint Domnius, built in the twelfth century. As the seat of the Archdiocese of Split-Makarska, it remains one of Split's most recognizable landmarks and is registered among Croatia's Cultural Goods.
