Novoanninsky
The Buzuluk valley around Novoanninsky was home to Don Cossack settlements long before the later town arose. Nearby Filonovskaya appears among the Cossack towns on the river in a list of 1698. Its wooden church of Saint Paraskeva was consecrated in 1728, serving a community on the Khopyor–Buzuluk plain. Rivers linked these stanitsas to the Khopyor and the Don, while their farmsteads spread across the surrounding steppe and floodplain.
