Trongzund Fort

The fortress of Trongzund (or Trångsund, lit. narrow strait) was built by the order of Peter the Great in the beginning of the 18th century after the Tsardom of Russia had captured the area from Sweden during the Great Northern War. In 1812, Trongzund was included by Alexander I into the newly created Grand Duchy of Finland.
