Bojnická Jeskyne is a castle cave, which means it is located below Bojnicky Zámok (Bojnice Castle) and integral part of the building. If you want to visit the cave you have to visit the castle, and you will get a cave trip including ghost stories.

The original castle which existed in the 12th century was a wooden fort. During the 13th century the owners, the Poznanovec family, continually transformed it into a stone castle. In the 16th century the castle expanded by two additional wings. In 1644, Bojnice was given a baroque make-over by the current owner, a Hungarian noble family named Pálffy. The last noble owner of the castle, Count Ján Pálffy (1829-1908) hired Austrian architects in 1888, to renovate the zamok. This resulted in the look of the castle we see today. And also it revealed a hidden secret after centuries: the existence of a cave below the castle.

The castle stands on a travertine hill. Travertine is a rather soft sort of limestone, formed very recent (in geologic terms) by depositing from limestone saturated spring water. This process also produces caves by enclosing spaces by irregular growth of the limestone deposits. The cave is a Speleologytufa cave, which is a primary cave, a cave formed together with the surrounding rocks. The cave is more or less a single circular chamber, 26m below the level of the fourth courtyard from which the castle well decends into the cave. It is 22m in diameter and is 6m high. Two ponds in the cave are probably connected to other caves in this area.

There must have been a spring producing the water which formed the travertine. Most likely it was inside the cave, or see it this way: the cave is the former spring. The still existing spring was a wealth of the castle, an internal source of drinking water which could not be polluted by enemies. The water may be called mineral water, there are rumours that it once was a thermal spring.

There is archaeological evidence that the cave was used during the Stone Age.

Today Bojnice is a famous spa, and the castle is famous day trip destination. There are similarities to the architecture of Neuschwanstein in Germany, and of course to the castle at Disney World. The castle is open to the public, is museum and hotel.
