Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split, Croatia. These ruins are some of the most valuable surviving buildings of the Roman era on the Adriatic coast. Emperor Diocletian, who voluntarily gave up the throne of the Roman Empire, in the turn of the 4th century CE built the palace and after his retirement on May1, 305 settled here, on the beach, in the Illyrian province of Rome.
