The Triglav National Park (TNP) is the only Slovenian national park. The park was named after Triglav, the highest mountain in the heart of the park, which is also the highest summit in Slovenia (2864 m). The origin of the name Triglav is rather uncertain. Triglav (»three-headed«) owes its name to its characteristic shape as seen from the south-east side or to the highest Slavic deity who was supposed to have its throne on the top of the mountain. The mountain is a true national symbol and is featured on the national coat of arms and the flag.
