Built for use by Emperor Diocletian who in AD 305 became the first Roman emperor to voluntarily abdicate, the palace at Split on the eastern coast of the Adriatic is the preeminent classical heritage site in the region. The palace reflected contemporary Roman military encampments, complete with walls, towers, gates, and colonnaded streets all housed within striking fortification walls.
Most impressive of all are the remains of the palace buildings that include the peristyle, which served as an entry to the emperor’s Mausoleum, the Temple of Jupiter, and a large sky-lit domed reception area leading to the atrium.
Diocletian’s Palace was placed on the inaugural 1996 Watch list. Conservation efforts began in 2002, involving documentation, geo-technical and other analysis and conservation treatments. The marble of the Peristyle, a colonnaded courtyard in the complex, was successfully cleaned and completely conserved by 2006 using an innovative laser cleaning method. In addition, previously installed corroded iron clamps were removed and the columns, capitals and entablature consolidated. In July 2007, the southern portion of the west colonnade was conserved and completed. Work included cleaning, conservation and repair of stone and of the original plaster.
WMF was also involved in the repair and stabilization of the roof of the palace’s Temple of Jupiter which was completed in 2007. In 2008, scaffolding was installed along the eastern colonnade and is expected to be completely restored by 2010. The Restoration Institute of Croatia in Zagreb, the Ministry of Culture–National Trust Department Split, and the Agency of the Historic Core, City of Split were also involved with the comprehensive conservation plan for the site
Diocletian’s Palace in Split is a complex that served many purposes—a palatial residence, a fortified outpost of the Roman world, and a symbol of the refinement that ancient Roman artists, architects, and designers brought to buildings that were meant to signal the reach of Rome.
Even after the end of the Roman Empire, building continued at and near Diocletian’s Palace, much of which is in evidence today. Although some destruction of parts of the palace occurred, these adaptations and renovations during the medieval period and later assured that the palace complex survived. It remains one of the best-preserved examples of Roman architecture of its time.
