Borovsk () is a town and the administrative center of Borovsky District of Kaluga Oblast, Russia, located on the Protva River just south from the oblast's border with Moscow Oblast. Population: 12,000 (1969). History It is known to have existed since 1356 as a part of the Principality of Ryazan. In the 14th century, it was owned by Vladimir the Bold, but passed to the Grand Duchy of Moscow when his granddaughter Maria of Borovsk married Vasily II. In 1444, the St. Paphnutius Monastery was founded near Borovsk. Its strong walls, towers, and a massive cathedral survive from the reign of Boris Godunov. Two famous Old Believers—archpriest Avvakum Petrovich and boyarynya Feodosiya Morozova—were incarcerated at this monastery in the second half of the 17th century. The town was liberated by the Red Army on January 4, 1942.
