Diocletian retired to his homeland

Diocletian retired to his homeland, Dalmatia. He moved into the expansive Diocletian's Palace, a heavily fortified compound located by the small town of Spalatum on the shores of the Adriatic Sea, and near the large provincial administrative center of Salona. The palace is preserved in great part to this day and forms the historic core of Split, the second-largest city of modern Croatia.
