Snovsk
Snovsk was a fortified town above the Snov River, north of Chernihiv, later known as Sedniv. The chronicle first records it in 1068, when Prince Sviatoslav of Chernihiv defeated a much larger Cuman force nearby. The river and its high bank gave the settlement a strong position in the Severian lands. In the Cossack Hetmanate, Sedniv became a company centre of the Chernihiv regiment.
