The Emperor Diocletian's Palace was built in the early years of the 3rd century in the southern cove of Split Peninsula. It was built as a fortified castle - castrum, from local material, stone from Brač and nearby quarries while numerous decorative elements were brought from Egypt and Greece. The rectangular floor area of 30,000 m2, was divided by two main streets - Cardo and Dekumanus, on four quadrants. It was bounded by the ramparts and towers, and there were four entrances to the palace, each on one side. The southern part of the palace was intended for the emperor and his family while the army was in the north part. The southern half floor is almost fully known while the north, due to numerous remodeling is less known. A similar situation is with decorative elements (with the exception of decorations of the northern doors). After the death of Diocletian, life in the palace continues, at the beginning of the seventh century it becomes a refuge for many Salonitian refugees fleeing from Avars.
