Derbent instance of city or town
Etymology
Derbent is derived from Persian "Darband" (Persian: دربند, lit. 'Door/opening in a Barrier', from dar “door/gate” + band “barrier/dam”, lit., “gate in the barrier”), referring to the eastern-most pass in the high Caucasus Mountains (whence the putative "barrier/dam") on the beaches of the Caspian Sea. (The other pass, the Darial Pass, is in Central Caucasus Mountains, and likewise carries a Persian name, standing for "the Alan Pass/gate" –  with the Alans being the modern Iranic Ossetians.)
It is often identified with the Gates of Alexander, a legendary barrier supposedly built by Alexander the Great in the Caucasus. The Persian name for the city came into use at the end of the 5th or the beginning of the 6th century AD, when the city was re-established by Kavadh I of the Sassanid dynasty of Persia, but Derbent was probably already in the Sasanian sphere of influence as a result of the victory over the Parthians and the conquest of Caucasian Albania by Shapur I, the second shah of the Sassanid Persians. The geographical treatise Šahrestānīhā ī Ērānšahr written in Middle Persian mentions the old name of the fortress – Wērōy-pahr (The Gruzinian Guard):
