Pokrovskoye
Pokrovskoye, later called Sengiley, stood on the high right bank of the Volga south of Simbirsk. Its settlement began as a frontier post established in 1666 by the voivode Ivan Dashkov to protect communities south of the Simbirsk defensive line. Three service settlements grew here and were joined as the village of Pokrovskoye, named for its church. In 1780 the village became the district town of Sengiley, overlooking the great river route.
