The Triglav National Park 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.
The Triglav National Park extends along the Italian border and close to the Austrian border in the north-west of Slovenia, that is, in the south-eastern section of the Alps. Its territory is nearly identical with that occupied by the Eastern Julian Alps. The park covers 880 square kilometers, or 3% of the territory of Slovenia. The Triglav National Park is among the earliest European parks; the first protection dates back to 1924 when the Alpine Conservation Park was founded. The principal task of the Triglav National Park Public Institution is the protection of the park, but it also carries out specialist and research tasks.
