Nyenschantz (Swedish: Nyenskans; Russian: Ниеншанц, romanized: Niyenshants; Finnish: Nevanlinna) was a Swedish fortress at the confluence of the Neva River and Okhta River, the site of present-day Saint Petersburg, Russia. Nyenschantz was built in 1611 to establish Swedish rule in Ingria, which had been annexed from the Tsardom of Russia during the Time of Troubles. The town of Nyen, which formed around Nyenschantz, became a wealthy trading center and a capital of Swedish Ingria during the 17th century. In 1702, Nyenschantz and Nyen were conquered by Russia during the Great Northern War, and the new Russian capital of Saint Petersburg was established here by Peter the Great the following year.[1]
