Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
Architecture
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades. The southern façade has no towers, because it was rising directly from the waters of the sea. The design of the palace is a mix of villa and castrum architecture. The Emperor’s apartments were located on the southern part of the complex - along the seaside.
Only the foundation and lower floors of these apartments have survived to our days. Diocletian’s octagonal mausoleum (later was reconstructed into a Christian church - one of the oldest in the world) and 3 temples were also located in the southern part of the palace. One of the temples was later turned into a baptistery, the other two were destroyed.
On the crossroad of the two main roads of the palace, the so called Peristyle is located. The Peristyle is a rectangular open court decorated with colonnade and intended to become the heart of the palace, where the most powerful Roman citizens were gathering.
Here and there in the palace one can find antiques, including three 3500 years old sphinxes, brought to Split from Egypt for the Emperor.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
