Veliky Ustyug
In 1613, during the Time of Troubles, Veliky Ustyug was besieged by Polish troops but never taken. At the junction of important trade routes, the town turned into a significant commercial and industrial center in the 16th and 17th centuries. Veliky Ustyug area was the birthplace of the explorers Semyon Dezhnyov, Yerofey Khabarov, Vladimir Atlasov, and of St. Stephen of Perm. Veliky Ustyug lost its key role as a river port with the diminishing importance of the Sukhona River route for trade between China and western Europe, which started with the foundation of Saint-Petersburg in 1703, whereby the trade was diverted to the Baltic Sea.
