The cathedral serves as the seat of the Archbishop of Split-Makarska.
The structure was originally intended to house the sarcophagus of Diocletian, the only Roman emperor to abdicate his throne.
The Romanesque bell tower underwent a major reconstruction in the early 20th century after partial collapse.
The cathedral's crypt is dedicated to Saint Lucy, the patron saint of eyes.
The original Roman columns and a frieze depicting Diocletian and his wife still surround the interior of the rotunda.
The cathedral's construction demonstrates a rare continuity of use from a pagan imperial mausoleum to a Christian liturgical space.
Saint Domnius Cathedral is the world's oldest Catholic cathedral still in use in its original structure. It was originally built as the Mausoleum of Roman Emperor Diocletian in the 4th century. The structure is situated within the remains of the Diocletian's Palace, a UNESCO World Heritage site. Its octagonal design reflects Roman imperial architectural influence, later adapted for religious use in the 7th century. The cathedral is famous for its wooden entrance doors, carved in 1214 by Andrija Buvina, which depict scenes from the life of Christ. A prominent Romanesque bell tower was added between the 12th and 16th centuries. The interior features an intricate 13th-century pulpit and a 15th-century altar. It serves as both a place of worship and a historical monument.
