Inside the Schloßberg (castle rock) beneath the castle of Homburg eight huge caves exist. The biggest one is the Schloßberghöhle (castle rock cave) we describe on this page. There is a similar cave of the same type called Schlangenhöhle in the suburb Schwarzenacker. It was once open to the public but is now closed for many years.

Probably during the early Middle Ages, using the softer layers, escape tunnels for the castle were dug through the sandstone. Later a special layer of the sandstone, which is very soft and easily breaks into small crumbs, became rather valuable. It was used for mortar and for cleaning wood and stone floors. It was also a raw material for producing glass and moulding sand for the iron industry. To mine the sand, the workers just followed the soft layers underground. The traces of their Medieval tools are still visible on the walls. As a result, this are not caves, despite the name. Caves are natural hollows, caverns like these are called quarries or mines.

Such sandstone quarries are abundant, but the Schloßberghöhlen declare they were the biggest in Europe. At least they have five kilometers of passages on 12 levels. The bigger chambers have arched ceilings, like ellipsoid cupolas with nice colour patterns from the different coloured layers of sandstone. It seems the cupolas are a result of the breakdown of rocks from the ceiling. This may also be a reason for the expensive restauration during the last years. The path is now roofed so visitors can not be hit by falling rocks.
