Ajdna (1064 m) is a peak in the Karawanks in the Municipality of Žirovnica in the Upper Carniola region of Slovenia. Access to it is easiest from the village of Potoki in the neighbouring Municipality of Jesenice. A settlement from late Antiquity has been found just below the summit and evidence shows that it was probably inhabited much earlier. Excavations began in 1976. Most evidence is from the period immediately after the collapse of the Roman Empire (476 AD), when it seems locals moved to the safety of the peak from the valley below during a period of upheval and migration of various Germanic and Slavic tribes through the region.
Ajdna is an amazing view point, both in the east and in the west direction and this is probably one of the reasons why it was popullated so early in history.
