The Caspian “Sea”—geographically more correctly an inland saltwater lake, the biggest of its kind in the world—is bordered by five modern nations, Kazakhstan and Russia (to the north), Azerbaijan (west), Turkmenistan (east) and Iran (south). With a melting pot of ethnicities in the region, below we will meet some medieval cities situated on the Caspian littoral that prospered for a time during the Middle Ages before vanishing entirely from history.
Lost city of Aktobe–Laeti: Archaeologists whose fieldwork focuses on the Caspian Sea and Caucasus regions have had much to occupy themselves with in recent decades. Systematic excavations started in the 1970s and have unearthed hitherto-disappeared sites like Aktobe–Laeti, a buried urban settlement on the Great Silk Road route that thrived in the 14th and 15th centuries. Atkobi–Laeti is located in the Atyrau (western) region of Kazakhstan. Archaeologists discovered that the settlement contains three cultural layers on top of each other (cf. Troy). Furnaces and fragments found among the debris point to the erstwhile city having skilled artisans in metalwork and pottery crafts. Many of the newly unearthed artefacts are now on display at the local history museum [‘Ancient Land of the Caspian Sea Holds Secrets of the Past’, Aruzhan Ualikhanova, The Astana Times, 15-July-2023, www.astanatimes.com].
Reconstructing a Golden Horde settlement: It’s estimated that at its peak Aktobe–Laeti housed around 10,000 inhabitants who traded their goods and wares with travelling foreign merchants. It’s key position on the Silk Road linking Central Asia and the lower Volga and evidence of the minting of coins suggest that the city was a prosperous one during these times. Traces of a substantial urban settlement in Aktobe–Laeti having existed, contradicts the established view that the peoples of the Caspian Sea led exclusively nomadic lives (Ualikhanova).
In the 14th century this important city of commerce could be identified on maps of Italian travellers but by the 16th century Aktobe-Laeti had vanished without a trace. There are two theories put forward that account for it’s sudden disappearance – it was submerged under the rising waters of the Caspian, or the city was destroyed by Timur of Samarkand in his vast empire-extending, take-no-prisoners rampage across central and western Asia (Ualikhanova).
Sabayil castle, Atlantis for real: Climate change, the damming of some 100 rivers which flow into the sea including the Volga and the flow-on effects of the Aral Sea disaster, have all resulted in a shrinking of the Caspian and an on-going drop in the sea-level. The singular upside of this ominous ecological change, perhaps for archaeologists alone, is the surfacing of the upper sections of the long-disappeared Sabayil (or Bayil) Castle. The structure, built by Shirvanshah Faribirz III in 1232–1235 as an off-shore watchtower 350m from the shoreline to give the citizens of Baku advanced notice of impending attacks on the city. In 1306 the castle sank under water due to a mega-earthquake. The now visible tops of the towers reveals huge stone tablets engraved in both Arabic and Farsi script and decorations depicting imaginary animals and human faces [‘As the Caspian Sea Disappears, Life Goes on for Those Living by Its Shores’, Felix Light, Moscow Times, 27-Apr-2021,

Caspian cities of the Khazar Khanate: Lost cities were also a feature of the medieval Khazaria Kingdom (a large area mainly to the north and northwest of the Caspian Sea). Prominent among these were Ithill (sometimes written “Atil”) and Balanjar. Ithill’s precise location is unknown, however Russian archeologists claim to have discovered the site of Ithill (near Astrakhan in Northern Dagestan), having unearthed a fortress, flamed bricks (a speciality of the Khazars) and yurt-shaped dwellings. The claim has not been substantiated. On the Silk Road route, Ithill, the Khazaria capital at one stage, at its zenith was a major centre of trade, including the Khazaria slave trade. Ithill’s road to ruin and downfall began in the 10th century after the city was sacked by Kievan Rus led by Prince Sviatoslav I. It may have been rebuilt afterwards but it was again decimated in the 11th century and wiped off the map for keeps. Balanjar was also a capital of Khazaria for a time and a city of considerable importance. It suffered the same fate as Ithill, decimated by nomadic conquerors (in the Arab-Khazar wars), rebuilt but went into terminal decline and was no more heard of after ca.1100𖤓.
Abuskūn: Medieval Persia was the site of a lost city on the southwestern shore of the Caspian Sea, the port of Abuskūn. It’s location is uncertain but most scholars place it in within the Gorgān region. Abuskūn was a prosperous trading hub for its merchants who traded as far away as the land of the Khazars on the Volga trade route. The city’s wealth and vulnerable location made it a sought-after prize for the Rus and their Caspian expeditions. After 1220 Abuskūn is not mentioned in the documents, although in the 14th century a Persian geographer wrote that it had been an island in the Caspian which was submerged due to the sea’s rise in level.
Abandoned Dekhistan in the desert: Modern Turkmenistan is host to one or two lost cities of its own. The most significant was Dekhistan, aka Dekhistan-Misrian (S.W. Turkmenistan), near the eastern shore of the Caspian Sea…a ruined Silk Road city but at its peak (11th century) a major economic centre and the foremost medieval oasis in the region. It managed to survive the Mongol invasion albeit weakened, limped on till the 15th century but was ultimately undone by large scale deforestation precipitating an ecological disaster (failed irrigation system), turning the city into a ghost town. All that remains are mud-brick foundations, the outlines of a few caravanserais and what’s left of several minarets in varying degrees of decay [‘Ancient settlement of Dekhistan’, Silk Road Adventures, www.silkadv.com].
Derbent continuity: Derbent in the Dagestan region of Russia differs from the impermanence of these other medieval Caspian cities in it having achieved a continuity of existence right through to the present day. Archeological diggings reveal that the city has clocked up nearly 2,000 years of continuous urban settlement. The existence of Derbent (romanised as “Derbend”, from a Farsi word meaning “gateway”) as a fortified settlement, was known by Greek and Roman authors as early as the 3rd century BC [‘Citadel, Ancient City and Fortress Buildings of Derbent’, UNESCO, www.whc.unesco.org]. Derbent’s strategic location, nestled tightly between natural barriers—the Caspian Sea and the Caucasus Mountains—has seen control of it pass from empire to empire – Persian, Arab, Mongol, Timurid, Shirvan and finally Russian§. Under the Persians it formed part of the northern lines of the Sasanian Empire.

𖤓 another Khazar city, Samandar—thought to be situated on the western shore of the Caspian roughly midway between Atil and Derbent—was also lost to history during this period
§ so prized because it allowed rulers of Derbent to control land traffic between the Eurasian Steppe and the Middle East [‘Derbent’, Wikipedia, http://en.m.wikipedia.org]
