The Dobrá Voda castle was built on the site of an earlier castle in the first quarter of 13th century in the mountainous terrain on one of the roads that cross the crest of a small Carpathian Mountains. It was first time mentioned in 1263. In ancient times, the castle formed an elongated structure of the palace, which was close to both sides of the four-sided tower, a palace located on the southeast side of the associated itself another part of the castle chapel ending. The castle, originally the property of the king, became the property Stibors Stiborice in the 14th century and since 1436 it was in the possession of family Orszagh.
In the end of 16th century castle owners started to secure the gate and restored the lower court, where they added a few strongholds in the fortification wall. The uprising of Francis II. Rákóczi (d. 1703) badly damaged Dobrá Voda castle and it was burned in 1762. After that it was a prison.

Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
