a tribute to Saint Apollinaris
The eastern gate of Diocletian's palace, which is called the Silver Gate, was a tribute to Saint Apollinaris, a saint who was around at the beginning of Christianity throughout the Mediterranean region. The imperial palace was converted, during the late antiquity, probably during the 6th Century, into a church where St. Apollinaris supposedly protected, with his fantastic powers, the city from invasions, and people entering the palace grounds. A part of the walls and the door were incorporated into the structures of the different buildings around. This was the case for example of the Church of the Holy Innocents, which was later destroyed during the Second World War.
