The Kilianstein is a free-standing pinnacle of rock in the eastern part of the Sembach valley in central Germany. It stands about 800 m east of the (upper) village of Winterstein on the northern slopes of the Thuringian Forest.
The pinnacle is about 15 m high and some 500 m above sea level. It consists of relatively crumbly quartz porphyry and is visited, albeit rarely, by sports climbers. Several trails are signposted from here, climbing routes have been established on the rock and on the top is a summit register.
This type of rock, very unusual in this area, fired the imagination of ordinary people centuries ago. They often linked incomprehensible phenomena and mysterious places with the work of the devil. According to a Winterstein legend, this rock was formed when, in ancient times, the devil rammed his walking stick into the ground in anger at the success of the missionary St. Kilian who came from this area, and the tip of his stick remained embedded.[1]
