Burgstallkogel (Sulm Valley)
The Burgstallkogel (458 m; also known as Grillkogel) is a hill situated near the confluence of the Sulm and the Saggau river valleys in Southern Styria in Austria, about 30 km south of Graz between Gleinstätten and Kleinklein. The hill hosted a significant settlement of trans-regional importance from 800 BC to about 600 BC. Surrounding the hill is one of the largest iron age hill grave necropolises, originally composed of at least 2,000 tumuli, that exists in continental Europe.
