The Demänovská Cave of Freedom is located in Slovakia and is part of the Demänovská Cave System that is more than 41 km long. The cave system stands out for the diversity of structures and stone, which have a great variety of shapes and sizes and a play of colors and tones. There are imposing halls and domes linked by corridors, as well as the Demänovka stream, which is part of the cave system.
The Demänovská Cave of Freedom was discovered in August 1921 by a professor from the country named Alois Král, who entered it through the Demänovka sinkhole. He found an impressive watercourse and a magnificent set of spaces, which made the cave originally receive the name "Temple of Liberty". The life in the cave reflects the presence and quality of the water. Largely because of their importance as a waterfowl biotope and underground wetland, the Demänovská Cave of Freedom and other caves in the Demänovská Valley are included on the List of Wetlands of International Importance under the Convention on Wetlands.
The cave was opened to the public three years after its discovery, it has a length of 8,400 m of which 1,600 are visited. The variety and beauty of its concretions, its spacious underground rooms and the incredible colors that the chemical reactions of iron and manganese print on its walls make it one of the most beautiful caves in Europe.
The Slovak Mint, Mincovňa Kremnica, taking advantage of the centenary of its discovery, has issued a 20-euro facial silver coin for the occasion.
