Feengrotten

Feengrotten, meaning "Fairy Grottos," are a series of show caves located in Saalfeld, Thuringia, Germany. They are renowned for their extraordinary dripstone formations, particularly the colorful and translucent stalactites and stalagmites. The caves were discovered in 1835 by miners and were opened to the public in 1913.

The Feengrotten are considered to be among the most beautiful and colorful stalactite caves in the world. The unique colors are attributed to a variety of minerals, including iron oxides and manganese oxides, which are dissolved in the groundwater and deposited over thousands of years. The constant dripping of water creates these intricate formations, with some stalactites reaching lengths of several meters.

The caves are organized into three main grottoes: the Grottenmutter, the Großer Saal, and the Tiefes Tal. Each grotto features distinct formations and offers a unique visual experience. Guided tours are available, taking visitors through the illuminated pathways that showcase the natural wonders of the caves. The temperature inside the caves remains constant year-round, around 10 degrees Celsius, making them a popular attraction regardless of the season. The Feengrotten are a significant natural monument and a testament to the slow, artistic work of geological processes.
