The cave was discovered in 1952 during explorations aimed at reviving former mining activities.
Unlike many limestone caves, these formations are primarily created by mineral-rich water leaching through alum slate rather than pure limestone.
The cave system serves as a natural habitat for several species of bats during their hibernation period.
It is officially recognized as a 'National Geotope' due to its distinct geological profile.
The 'Fairy Grotto' section features formations that have been nicknamed for their resemblance to magical landscapes.
The mine was originally operated for the production of alum, an essential material for the tanning and dyeing industries in the 17th and 18th centuries.
Morassina is a unique show grotto situated within a former alum slate mine in the Thuringian Forest near Schmiedefeld. The site is characterized by an extensive collection of colorful, naturally occurring stalactite and stalagmite formations. These mineral deposits were shaped by groundwater filtering through layers of colorful slate, resulting in vivid ochre, red, and brown hues. The cave system is part of a larger historical mining complex that dates back to the 17th century. Visitors explore the subterranean world via a guided tour path that traverses the main accessible caverns. The site is notable for its constant internal temperature, which remains stable regardless of exterior weather conditions.
