Poshekhonye

Poshekhonye lies where the Pertomka joins the Sogozha, in a wooded country named for the Sheksna and its tributaries. The older settlement was the village of Pertoma, whose river name has Finno-Ugric roots. In the seventeenth century it became an administrative centre of the surrounding district, with the governor's office based there from 1680. Under Peter I, Pertoma also served as a provincial centre for a time.

In 1777 Catherine II's administrative reforms joined Pertoma to the neighbouring village of Troitskoye and made the settlement the district town of Poshekhonye. Its new name recalled the broader region along the Sheksna. Rivers and forests continued to shape the life of the district, while the town brought local administration and trade together near the confluence.
