|Elevation||1,400 m (4,593 ft)|
The pass is located in the state of Carinthia, connecting Glödnitz in the Gurk valley with Stadl on the Mur river, beyond the border with Styria. The pass height comprises a dispersed settlement with a high-altitude sanatorium (Luftkurort) and an Alpine lake (Flattnitzer See). It is a popular destination for hikers and for cross-country skiers in winter.
The pass was possibly known in Roman times, it was first mentioned in a 898 deed issued by the Carolingian emperor Arnulf. In 1173 the Gurk bishops had a Romanesque chapel erected, dedicated to St John the Baptist, which was rebuilt as a parish church with an adjacent hospice building about 1330. The bishops used Flattnitz (from Slovene: blato, "moss") as a summer residence. The pass height was devastated by invading Ottoman forces in 1478. In the 17th century, Flattnitz was a mining area for silver, iron ore, and lead.
