gorodishche did not, and was likely to represent the hitherto unlocated city of Gülistan, which was developed by Jani Beg and rivaled Sarai as a khan's residence and mint in the 1350s and 1360s but then declined. This conclusion quickly gained support among the experts, and the present general consensus is that Selitrennoe gorodishche () is "New Sarai", while Tsarevskoe gorodishche () is Gülistan. There is currently no consensus on the location and identification of "Old Sarai". Some scholars suppose that it was a less impressive settlement whose ruins are yet unnoticed or obscured under those of "New Sarai" at Selitrennoe gorodishche, or were destroyed by changing water courses and levels. Others have sought a suitable archaeological site downstream of Selitrennoe gorodishche to identify with "Old Sarai". Here there are extensive remains of Golden Horde settlements, especially at Aksarayskoe gorodishche (at modern Lapas, medieval Dawlat-Khan), and at Akhtubinskoe gorodishche (at modern Komsomol'skiy, medieval Ak-Saray). Apart from a tentative suggestion for Vol'noe 15 km downstream from Selitrennoe, Akhtubinskoe gorodishche at Komsomol'skiy has also been suggested, and a case has been made for Krasnoyarskoe gorodishche in Krasny Yar, where the necropolis on the neighboring Mayachny hill has yielded some coins from the 13th century. The question remains open. The account of William of Rubruck (1254) ensures a location for the Sarai of Batu at or slightly above the apex of the Volga Delta, on the left edge of the Volga-Akhtuba river sistem. This is something possibly compatible with Selitrennoe gorodishche, or perhaps rather with a site farther downstream, between it and the apex of the Delta. This is also consistent with the account of Abū al-Fidāʾ (1321), which places Sarai on the Volga only 2 days above the Caspian coast, and with that of Ibn Baṭṭūṭa, who reached Sarai 3 days after (Old) Astrakhan. Pegolotti (writing in 1335–1343) gives a single day's journey between Sarai and Astrakhan, while the Nikon Chronicle cites 2 days for the same journey. Only the account of William of Rubruck refers without any doubt to "Old Sarai", since it dates to the reign of Batu. If "Old Sarai" and "New Sarai" coexisted for some time at some distance from each other, "Old Sarai" ought to be sought downstream of "New Sarai". This might be confirmed by a 15th-century map from the Franciscan monastery of Lesina (Hvar), which places Saray (apparently "New Sarai" at Selitrennoe gorodishche) on the
