König-Otto-Tropfsteinhöhle
The 109th longest cave in the world
The König-Otto-Tropfsteinhöhle (lit. English: King Otto stalactite cave) is a natural karst cave near Sankt Colomann (Velburg), a district of the Upper Palatinate town of Velburg in the southeast of the district of Neumarkt in der Oberpfalz, Bavaria, Germany. It is considered one of the most beautiful stalactite caves in Germany. It stretches for 450 metres (1, 480 ft), with approximately 270 metres (890 ft) accessible to visitors through a guided tour that takes about 30 to 40 minutes. The cave was discovered by shepherd Peter Federl on 30 September 1895, the name day of the Bavarian King Otto, hence the name. A significant addition to the cave's attractions occurred in Advent 1972 when an unknown section of the cave, known as the Advent Hall, was discovered. This part was later connected to the main cave and opened for public access. The König-Otto-Tropfsteinhöhle is part of the show caves that make up the Erlebniswelt Jurahöhle group.
