From the outside, the church has an octagonal layout and was once encircled by a roofed peripter supported by twenty-four
marble columns with Corinthian capitals, incorporating a portal of ancient Roman origin. A Baroque stone plaque, crowned with a tiara, emphasizes the church’s former metropolitan and primatial status, which the archdiocese retained until it was formally abolished by the papal bull
Locum Beati Petri in 1828. The interior of the church is circular in plan, covered by a dome and articulated by square and semicircular niches that once housed statues of gods and emperors. The inner space is encircled by eight Corinthian columns of red granite. Of particular interest are two ribbon-framed medallions, which archaeologists and local tradition in Split identify as portraits of Emperor
Diocletian and his wife
Prisca.
Portal One of the cathedral’s most celebrated features is its wooden doors, carved in walnut in 1214 by the Split native
Andrija Buvina. They are decorated with 28 carved scenes—fourteen on each wing—depicting episodes from the life of Christ, ranging from the
Annunciation by
Gabriel to the
Resurrection. The doors have survived to the present day in remarkably fine condition. Buvina’s doors are a rarity in European artistic heritage, as very few medieval doors made of wood have been preserved to this day.
Interior To the left of the entrance stands a hexagonal pulpit from the 13th century, made of costly green porphyry and once entirely gilded. The right side altar was dedicated to Saint Domnius, bishop of Salona and martyr. Its altar canopy (ciborium) was erected in 1427 by Bonino da Milano in the
Late Gothic style, while frescoes of the four Evangelists were added in 1429 by the Split painter Dujam Vušković. The left side altar, dedicated to Split’s co-patron saint, the Solin martyr Anastasius of Aquileia, was created in 1448 by the greatest Croatian architect and sculptor of his age,
Juraj Dalmatinac. Especially striking is the central relief on the sarcophagus depicting the Flagellation of Christ, where Dalmatinac portrays Christ as deeply moved by suffering and pain. The main altar was constructed between 1685 and 1689. In the northern niche stands an altar made in 1767 by the Venetian sculptor
Giovanni Maria Morlaiter; since 1770, it has housed the relics of Saint Domnius, transferred from Bonino’s altar. The most important works in the cathedral’s Baroque choir are the wooden choir stalls, originally placed before the main altar and carved in the first half of the 13th century. The cathedral’s bell tower, rising to 57 meters, is the most authentic example of medieval architecture in Dalmatia and was begun in the 13th century. It underwent extensive restoration and partial alteration at the turn of the 19th to the 20th century. Today, visitors can climb the bell tower’s stairs to the top, from where a spectacular panoramic view of the entire city of Split unfolds. The Cathedral of St. Domnius is composed of three different sections of different ages. The main part is
Emperor Diocletian's mausoleum, which dates from the end of the 3rd century. The mausoleum was built like the rest of the
palace with white local
limestone and
marble of high quality, most of which was from marble quarries on the island of
Brač, with
tuff taken from the nearby river
Jadro beds, and with brick made in
Salonitan and other factories.
Tower bell The
bell tower was constructed in the year 1100 AD, in the
Romanesque style. Extensive rebuilding in 1908 radically changed the Bell Tower, and many of the original
Romanesque sculptures were removed. The bell tower of the Cathedral of St. Domnius is 57 meters high and one of the most original church bell towers on the
Adriatic coast. Construction began in the mid-13th century and lasted until the mid-16th. Due to the extremely long construction period, it is a combination of
Romanesque Architecture and
Gothic architecture, but the styles are in excellent harmony. The Romanesque style prevails in the decorative elements, and the execution of architectural transparency belongs to the Gothic style of construction. The bell tower is a distinctive architectural work, specific for its slenderness and transparency, for its gradual narrowing towards the top and its integration into the ancient architectural environment, because the use of cornices and capitals, in the format of openings and arches, corresponds to the arcades of the Peristyle and the trabeation of the peripter of the mausoleum. The bell tower was thoroughly restored between 1890 and 1908. The top floor with hints of Renaissance style was completely changed to be in stylistic harmony with the other floors. Numerous ancient spolia and sculptures depicting griffins, lions, sphinxes and people were removed. Some fragments of the old bell tower are kept in the Split City Museum or have been incorporated into the Tusculum building in Salona. Later, in the 17th century a
choir was added to the eastern side of the mausoleum. For that purpose the eastern wall of the mausoleum was torn down in order to unify the two chambers. ==Treasury==
