History and Background
The Roman Period
Emperor Diocletian (Gaius Aurelius Valerius Diocletianus) commissioned the construction of his palace around 295 A.D., during his reign as one of Rome's most reformist emperors. Diocletian chose the location of Spalatum (the Roman name for Split) for its strategic position on the Adriatic coast and its proximity to his birthplace in nearby Salona.
The palace was designed as both a military fortress and an imperial residence, reflecting Diocletian's dual concerns with security and comfort. Construction continued until approximately 305 A.D., coinciding with Diocletian's abdication and retirement to the palace. The structure covered an impressive area of approximately 215 by 180 meters, with walls reaching heights of up to 28 meters.
The palace complex included numerous features typical of Roman imperial architecture: the emperor's apartments, administrative offices, temples, barracks for the palace guard, storerooms, and sophisticated water and heating systems. The design incorporated elements from Roman military camps, reflecting the militaristic nature of Diocletian's reign.
Medieval Transformation
Following the fall of the Western Roman Empire and the subsequent invasions of Dalmatia by various barbarian tribes, the palace fell into disuse as an imperial residence. However, rather than being abandoned, the structure was gradually repurposed by the local population.
In the 7th century, refugees fleeing Slavic invasions of the nearby Roman city of Salona sought shelter within the palace walls. This marked the beginning of the palace's transformation into a functioning medieval city. The palace's thick walls and fortified design provided protection, while its internal structures were adapted for residential and commercial use.
Medieval Development
During the medieval period, particularly from the 9th through 13th centuries, the palace complex underwent significant modifications. The medieval inhabitants constructed new buildings, subdivided existing Roman structures, and added defensive features including towers and fortifications.
A cathedral was built within the palace, ingeniously incorporating materials and architectural elements from Diocletian's ancient mausoleum. This cathedral, dedicated to Saint Domnius (the patron saint of Split), became the spiritual center of the medieval city and remains one of the most important religious structures in the complex.
Twelfth and 13th-century Romanesque churches were constructed throughout the complex, adding another layer of religious and architectural significance. These churches featured the characteristic rounded arches and solid construction typical of Romanesque architecture.
Renaissance and Baroque Periods
As Split developed into an important Venetian trading port, the city experienced renewed prosperity during the Renaissance and Baroque periods. Wealthy merchants and nobles commissioned the construction of elegant palaces within the palace complex, featuring Renaissance and Baroque architectural styles.
These later additions demonstrate the continuous evolution of the site, with each historical period leaving its mark on the urban fabric. Despite these modifications, the fundamental structure of Diocletian's Palace remained visible and recognizable, creating a unique archaeological and architectural record.
