“Usadba Ryazanka” is an estate of the Semenov family, situated in Chaplyginsky District of Lipetsk Region. It’s the birthplace of Pyotr Semyonov-Tyan-Shansky, a Russian geographer and statistician who managed the Russian Geographical Society for more than 40 years. He is determined to explore the largely unknown mountains of the Tian Shan.
The main house, an one-storey wooden building, and a large park of the estate have survived until the present time. It is now a historical and cultural site of regional significance which is a museum containing 12 exhibition halls.
