The southern gate (Latin: Porta Meridionalis) of Diocletian's Palace in Split, Croatia, built around AD 295-305 as a sea gate through which the emperor entered by boat. Unlike the palace's three other monumental gates, the Bronze Gate is notably smaller, has only a single wall, and bears no decorations. In Roman times the sea lapped directly against the walls here, and inhabitants reached the gate via basement rooms beneath the peristyle. During the Middle Ages it became known as the Security Gate, offering escape by sea in case of attack. Today it is the main entry from the Riva promenade to the old town.
