Obolensk

Obolensk stood on the Protva River in the upper Oka region. It was the centre of a small principality associated with Tarusa and later gave its name to a princely family. The town is mentioned in a chronicle in 1368, when Lithuanian forces marching toward Moscow captured it.

Moscow annexed Obolensk in 1494, and its princes continued in the service of the Muscovite ruler. The town later administered a rural district but lost its town status under Catherine II.
