The Korlatka Castle (Konradstein) was built in the mid-13th century as a watchtower on the route connecting the medieval Bohemia and Hungary. It is not known who built it, the first mention of the castle appeared in 1289 and connected it with a certain Ugrin. At the beginning of the fourteenth century, it was in the hands of the Austrian knight Ulving Harcendorf, who in 1314, the magnate Matthew Csák had to pay in exchange for the stronghold. In 1394, the castle passed from the king Sigismund into the hands of Stibor of Stiboricz. After him, the object often changed owners, and during the Hussite Wars it was the seat of knights-robbers. About 1444 raiders were driven away by the Bratislava townpeople. In 1645, the stronghold was occupied by the army of George II Rákóczi, and in 1704 there were kuruc rebels here. In the eighteenth century, the castle was deserted and since then gradually destroyed.
The stronghold consisted of an upper castle and up to three outer wards. Located the highest on a rocky hill, the oldest part of the complex, the upper castle consisted of a massive main tower, a residential house attached to tower from the north side and the defensive wall. The tower was a cylindrical construction, but set on a polygonal base. Its external diameter was 10.5 meters with a wall thickness of up to three meters. It probably played the role of bergfried, although small window openings suggest that it could also perform residential functions. The entrance gate to the upper castle was located on the north side.
To the north and south of the upper castle were small wards with economic buildings, which probably developed at the turn of the fourteenth and fifteenth centuries. The southern ward stretched on a rocky ridge extending around 50-55 meters and additionally securing the main tower. Apart from economic functions, the northern ward provided additional protection for the access road to the upper castle. The most distant ward extended on the eastern side and eventually formed in the first half of the 16th century. It was reinforced with a corner, cylindrical tower, a perimeter wall and on the east side with an additional, lower defensive wall with a gatehouse. The outer zone of defense was a moat with a drawbridge over it.
Small fragments of the perimeter walls and the main tower have survived from the upper castle, in a slightly better condition survived the fortifications of the outer bailey. Recently, restoration works have been carried out at the castle, vegetation overgrowing the stronghold has been cut down. Entrance to the ruin is free.
