Bojnice castle is a national cultural monument and museum at the same time. It is one of the most beautiful monuments in Slovakia and is visited by visitors from all over the world.
It is also one of the oldest and most distinguished of Slovak fortresses, standing on a travertine hill above the town. The first written records of its existence come from 1113 in a document from the Zobor abbey. In this Latin written document King Koloman confirmed the property as belonging to the Benedictine monastery of St. Hypolita in the upper Nitra.

Originally the fortress was made from wood and grew out of the older fortress. Gradually over the 13th century it was built up from stone as property of the Poznanovec family. The outer walls of the fortress were shaped according to the uneven rocky terrain, so creating the irregular outline with extended fortification.

At the end of the 13th century Bojnice was seized by the magnate Matus Cak Trenciansky and the fortress remained in his hands until 1321. After him, in the 14th and 15th centuries, ownership of the fortress changed hands between the following noble families : Gileth, Leustach and Noffry. The result of the building activities of that time is the preserved outline in the shape of an extended oval of the central living quarters of the fortress built around the small courtyard with well.

Bojnice fortress and its domain were always part of the Royal property, with the King handing out pledges or privilege of heritage to the given magnates.
