Ehrenfels Castle is located at an altitude of 1150 meters above the "Gföhler Wand" near Kammern and can only be reached in just under half an hour on a narrow, steep path that leads on from the neighboring Kammerstein Castle.
The effort of the climb is rewarded with a beautiful distant view over the Liesing Valley.
Only a few remains of the castle have been preserved, which are difficult to perceive from the road. The castle ruins are located on the top of the "Gfäller Wand" and is at an altitude of 1146 meters, one of the highest fortified buildings in Styria. Three sides around the castle drop steeply, towards the north a moat cut into the rock separates the castle from the mountain. A drawbridge led through the gateway into the courtyard, where, in addition to the keep, there was also a longhouse, a residential building measuring 12 x 7 meters.
The castle was probably built in the 13th century on the site of an older fortified building (possibly destroyed by an earthquake - the basis for the legend of the end of Ehrenfels). As a sign of the times, in the late Middle Ages the knights withdrew more and more to their valley castles and castle counts or administrators sat in the castles. The Lords of Ehrenfels themselves moved into the valley castle in Ehrnau as early as 1347. Most recently, Kammerstein Castle was probably the headquarters of the lords of the castle, who always had both castles in their possession.
Already at the beginning of the 15th century the castle might have been a prey of the flames. Large parts of the castle buildings were made of wood. This is one of the reasons why so few remains have been preserved. On a photograph from 1929, one can still recognize a larger wall remnant.
