It is in a place called Ukraine. This cave is the longest in Europe. It is also the seventh-longest cave in the world. It is the longest gypsum cave on Earth. Gypsum is a type of soft rock.

A group found the cave in 1966. They were part of a club called Cyclope. People have gone inside many times since then. They have held over 50 trips to study it. The cave is like a maze. It has many paths on different levels. Most paths are small. They are not more than 2 meters wide or tall. Some paths have lots of mud.

Inside, you can see many pretty things. Water seeps through the ground. This makes calcite speleothems. These are rock shapes that grow in caves.

You can also see gypsum crystals. Some crystals have many colors from salt. Some look like big flowers. We call these gypsum rosettes. Some of these are black. This is because of manganese oxide. This cave is a Natural Wonder of Ukraine.
