Jasmund National Park is a nature reserve on the Jasmund peninsula, in the northeast of Rügen island in Mecklenburg-Vorpommern, Germany. It features the largest chalk cliffs in Germany, the highest of which is Königsstuhl, rising to 161 m (528 ft) above the Baltic Sea. At 30 km2 (12 sq mi), Jasmund is the smallest national park in Germany. It was founded in 1990 by the last government of East Germany (GDR) prior to the German reunification. The park's beech forest was named as a UNESCO World Heritage Site in 2011, as an extension of the primeval beech forests of Europe site, due to being largely undisturbed since the last Ice Age.Photograph credit: Moahim
