Stužica is a uniquely preserved and undisturbed primeval beech forest of the Eastern Carpathians range. It is located in Slovakia and borders with Poland and Ukraine. The forest has been protected since 1908 and in 1993 the area was upgraded to a National Nature Reserve. In 2007 Stužica and several other locations in the range were declared part of the UNESCO World Heritage Site. Together with six components in Ukraine they form Primeval Beech Forests of the Carpathians with outstanding universal value.
