Schlossberg Caves
Schlossberghöhlen
Said to be Europe's largest artificial red sandstone cave system, with a 12-level labyrinth of golden-red tunnels beneath the castle hill in Homburg.
The Schlossberg Caves in Homburg are artificial caves dug since medieval times to quarry quartz sand. They have 12 levels totaling several kilometers, with layers of golden and orange-red sandstone domes that are spectacular. Some sections were used as fortifications and, during World War II, as air-raid shelters. Visits are guided and take about an hour. The caves are damp and cold, so bring a jacket. The summit also holds the ruins of Hohenburg Fortress. The caves are about 35 km from Saarbrücken, reachable by train to Homburg, then on foot or by car up the hill.
