The ruins of the Gothic Gymesz castle rise on the southern slope of the Dúň Mountain (514 m). They are located 5 km north of the village of Jelenec (in Hungarian Gýmeš). Picturesque tourist routes from the villages of Jelenec and Kostolany lead to them.
The castle was built in the second half of the 13th century in the place of an older stronghold. Until 1848 it belonged to the Forgacs family, which over the centuries has repeatedly rebuilt the stronghold, including after it was burned by the Turks in 1576 or the shelling of the prince of Transylvania by the troops in 1618. In the 17th century, the castle was twice looted by the Turks. For the participation of Szymon Forgacs in the Rakoczy Uprising, the castle was confiscated and put up for sale. Fortunately, it was bought by the Bishop of Nitra, a member of the Forgacs family, thanks to which he remained in the hands of the family until the 19th century.
