The castle complex was built in 1750 by the Gyurcsányi family from the Trencsény county, and after the family died out, it became the property of the Prónay family at the end of the 19th century. The Prónay family and its various branches had also residences in other settlements, and they owned several historic castles in Nógrád. The family was one of the oldest owners of Túrócz county, its first known representative received Tót-Próna as a donation back in 1279. In the post-Turkish period, they acquired significant estates in Nógrád County and became an important noble family here, so for example Pál Prónay was the ambassador of Nógrád County between 1725 and 1741. From him comes the baronial branch of the family, who owned several places in the county. Many of the family members were officials of Nógrád county. In the next two centuries they held various administrational offices. They performed as one of the county's public prosecutors and chief clerks, board judges and serf judges, deputy clerks, and representatives of the parliament also emerged from the Prónay family. During the 20th century Mihály Prónay was the family member who stood out, because in 1906 he became the mayor of Nógrád county. His widow, Felícia Batthyány, was the last resident of the Small Castle before World War II.

After the World War II, their original owners lost the castle complex and the buildings started to decay. It was not used as a representative residence for decades, its former furnishings destroyed or scattered. Some of the castle's buildings were given various functions: they were emergency housing, workshops, schools, medical clinics, industrial plants, offices, warehouses, miners' clubs, and many other functions, which led to the general deterioration of the buildings and architecturally unsuitable transformations.

The new owner aimed at giving the castle a modern form of use in line with its original values, so that it can be visited even after the complete restoration and renovation. This work was preceded by detailed scientific (archival, historical, art historical) research, and throughout the restoration, the planning and execution, as well as the design of the new buildings, were carried out with the involvement of heritage and monument specialists.

The owner of the castle received the Podmaniczky Award for the renewal of the built heritage.

Grand Castle

The Grand Castle is the most significant and architecturally the most valuable building of the complex. The U-shaped building was the scene of social life during the time of the Prónay family. Today, it serves the same function and hosts representative events, as well as awaits its guests with two exclusive suites.

Wine cellar

The oldest section of the cellar under the Grand Castle was built during the 17th century and has been restored to its original condition. It was used to store wines from the noble families' plantations in Petény. Today, the shelves are lined with the award-winning Csendes Dűlő wines from the Badacsony vineyard of the current owner family.

Small Castle

The architectural specialty of the Small Castle is that its neo-baroque residential units are organized in a square shape around the closed inner courtyard (atrium). Prónay family used to live in this building, so in addition to the rooms, there was also a kitchen and a bathroom in the Small Castle. Similar to the original function, salon and dining room is found next to the hotel's 3 suites, which are furnished with authentic furnitures and serves the guests' comfort.

Manor House

The old, 18th-century building of the castle was part of the Majorság buildings. During the time of the Prónay family, it gave home to the laundry room and other service units. Retaining the monument part of this building and extending with a modern hotel wing, an amazing harmony of the old and the new era welcomes the guests. There are 11 hotel rooms and one suite in the building.

Event hall

The reception, the restaurant, the almost 300 m2 event hall and 14 hotel rooms are located in the modern event building, directly connected to the castle park with huge glass surfaces. Guests arrive directly to the reception from the closed parking lot next to the event hall.

Spa Pavilion

The SPA is the island of relaxation, which was designed to offer everyone the opportunity to find the best way to relax.
