The Cathedral of Saint Domnius in Split, housed in the oldest building of all the cathedrals, the mausoleum of Emperor Diocletian built around 300 AD. on Peristyle Imperial square, with its 57-metre-high bell tower, is the trademark of the city. It is the place where the emperor, a great persecutor of Christians, determined as his last resting place, which became a cathedral in the 7th century, where the remains of St. Domnius and St.Anastasius (Staš), Christian martyrs executed in nearby Solin, were brought.
The most famous part of the cathedral are Andrija Buvina’s doorframes with scenes from the Gospels. From the pulpit is the side altar and through the altar ciborium, there are a series of frescoes. Every detail of this unique cathedral is admirable including the main and side altars and the sarcophagus.
