Blatná Castle is the town's main landmark. It is built on a rock surrounded by a moat, connected with a pond. The castle is narrow, U-shaped, with a tower in front to which the palaces from various periods attach. The castle is being restored with most of the works finished. It is open for the public, together with the castle park and deer park.
Under the Lev of Rožmitál family, the fortress was for the first time rebuilt in stone (the oldest parts being the tower and Rožmitálský Palace) and the surrounding marshes were changed into wide water trenches. A Gothic chapel was soon attached to the tower and palace. Lords of Rožmitál were continuously rebuilding and enlarging the castle, first with the so-called Old Palace, standing separatedly over the remnants of a Romanesque chapel. In 1523–1530, during the rule of Zdeněk Lev of Rožmitál, a new palace in a mixed Gothic-Renaissance style was appended under the guidance of renowned royal builder Benedikt Rejt and now is called Rejt's Palace.
During the rule of the Counts of Rozdražov, the Renaissance Rozdražovský Palace was built and became the last part of the castle. In the 18th century, the Serényi family had one wing of the castle rebuilt in the Baroque style and also erected many Baroque statues in the town and its surroundings. In 1850–1856, the castle received its last rebuilt, which gave it its contemporary neo-Gothic look.
The castle park spreads next to the castle on an area of 42 ha (100 acres). The park was created as an English landscape garden at the beginning of the 19th century by František Hildprandt. Its part close to the castle surrounds a large meadow with very old solitary oak trees. Beyond the meadow are preserved old woods with alleys, swamps, streams with footbridges over them, artificial caves, remnants after placer mining and an Empire style summer house. Its part is also a deer park. A herd of tame fallow deer freely roams the park.
References:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
