Veliky Ustyug is a town in Vologda Oblast, Russia, located in the northeast of the oblast at the confluence of the Sukhona and Yug Rivers. As of the 2010 Census, its population was 31,665.Veliky Ustyug has a great historical significance and was one of the major cities of the Russian North. It preserved some of the past urban structure and many of the architectural monuments, it was completely deprived of its leading role and is now merely a tourist attraction.Location and etymologyVeliky Ustyug is close to the confluence of the Sukhona (flowing from the west) and the Yug (from the south) rivers. Downstream from this confluence the rivers form a single waterway known as the Northern Dvina, sometimes referred to as the Little Northern Dvina. The historical center of the town is on the left (high) bank of the Sukhona and, in contrast to many historical Russian towns, there is an embankment along the Sukhona.Dymkovskaya Sloboda and Troitse-Gledensky Monastery are on the right bank of the Sukhona. New parts of the town, mostly industrial areas, face the Northern Dvina. The only bridge in Veliky Ustyug is across the Sukhona upstream of the town center.Previously, Gleden was a fortress, and the left bank of the Sukhona was a posad—a territory outside the fortress populated by craftsmen. In the 15th century, the fortress was destroyed in an attack by Vyatka army, and the new fortress was built in the former posad area. The fortress was demolished when it became apparent than no military threat to Veliky Ustyug exists.
