Military significance. A castle stood here as early as the early Middle Ages, which was converted into a Renaissance fortress in the 16th century. After the demolition of this structure by Napoleonic troops in 1809, the hill did not regain military significance until 1943.

A total of approximately six kilometers of tunnels (1) with 21 entrances were built around the hill. These were labeled "A" to "X," although not all entrances were completed or assigned all letters. The code name for this company may have been "Felshütte," but this cannot be proven beyond doubt.

Today, in addition to the mining and factory railway museum, the Graz fairytale railway, the casemates, the Schloßberg lift and the cathedral in the mountain are located in the Schloßberg tunnel. Since the rock is around 4°C, the temperature inside the tunnel is 8 to 12°C all year round - so visitors should dress warmly enough even in summer.

A deep cave, the so-called Great Weather Hole, is on the way. It's a steep descent there.
