Iron Gate

Gates of Alexander

The Gates of Alexander, also known as the Caspian Gates, are one of several mountain passes in eastern Anatolia, the Caucasus, and Persia, often imagined as an actual fortification, or as a symbolic boundary separating the civilized from the uncivilized world. The original Gates of Alexander were just south of the Caspian Sea, at Rhagae, where Alexander crossed while pursuing Darius III. The name was transferred to passes through the Caucasus, on the other side of the Caspian, by the more fanciful historians of Alexander.

Iron Gates (Algeria)

The Iron Gates are a mountain pass in the Bibans in Algeria. They gave their name to the Biban Range.

Iron Gate (Antioch)

The Iron Gate is a sixth-century dam which is located in the mountains to the east of Antakya in Turkey. It is one of the earliest known arch dams and is now the oldest to survive. It was built in the mid-sixth century on the order of the Byzantine emperor Justinian I to collect and slow the waters of the Parmenios stream, which in the rainy season could cause torrential floods endangering Antioch's city centre. Previous attempts to channel the floodwaters into underground passageways had not fully solved the problem.
