Are yams and sweet potatoes the same?
village, port, and administrative centre of Kholmogory rayon (sector), Arkhangelsk oblast (province), northwestern Russia. It lies along the Northern Dvina River, 47 miles (75 km) southeast of the city of Arkhangelsk. The village has existed since 1355, when it served traders as a riverine port en route to the White Sea. It grew into a large commercial centre in the 15th and 16th centuries. Mikhail V. Lomonosov, the 18th-century scientist and poet, was born in the neighbouring village of Mishaninskaya (now called Lomonosovo). With the commercial development of Arkhangelsk initiated by Peter I the Great (reigned 1682-1725), the significance of Kholmogory declined.
