Fruška Gora National Park
Vojvodina, Serbia · built 1960
Fruška gora (Serbian Cyrillic, Hungarian: Tarcal-hegység) is a mountain in Syrmia, with most of the mountain being part of Serbia and its westernmost edge extending into eastern Croatia. The Serbian part of the mountain forms the country's oldest national park. Sometimes also referred to as the Jewel of Serbia, due to its largely pristine landscape and protection effort, or the Serbian Mount Athos, being the home of a large number of historical Serbian Orthodox monasteries.
