Voin is an ancient Russian frontier town within the Principality of Pereyaslavl, first mentioned in 1055 in connection with the victory of the squad of Prince Vsevolod Yaroslavich over the torques . Located on the right bank of the Sula River near its confluence with the Dnieper. Currently, the place where the city stood, and later there was the village of Voinskaya Rowing, flooded with waters of the Kremenchug reservoir.
Voin occupied an area of 4.6 hectares and was surrounded by a horseshoe-shaped unpaved shaft 400 m long, containing two rows of wooden stands of logs, in which the military garrison was located. On the fourth side of the city was protected by Sula River. Posad, protected by natural barriers, occupied an area of 23 hectares. A burial ground was found to the west of the city.
Voin was a border fortress, to the south of which the Polovtsian steppes extended. At its walls, clashes repeatedly occurred between Russian and Polovtsian troops. Voin also had a harbor where ships stopped on their way from the Varangians to the Greeks.
For the first time, the Voin was localized at the end of the 19th century by archaeologist V. G. Ljaskoronsky . The excavations showed that the most ancient residential and military buildings of the Warrior date back to the era of Vladimir Svyatoslavich . By the middle of the XII century, Voin became a relatively large city, however, it was taken and plundered by the Polovtsians in 1185 and finally destroyed as a result of the Batu Khan invasion in 1239
