The Vildštejn castle (Wildstein) in Skalná was founded by the noble family Notthracht towards the end of the 12th century. It was first mentioned in 1224 and stands on a rock protruding from the Soosbach (Sázek) valley. The stream could be dammed earlier, so that the main castle was surrounded by water all around. The oldest parts of the castle, the portal to outer ward, part of the surrounding wall , the gateway to the main castle flanking the keep and the two bullets comprehensive chapel, are the Romanesque style.
In the 14th century at the latest, the construction of one supported on the ground floor with mighty belt arches and on two central pillarsresting cross vault . This Gothic building adjoins the Romanesque chapel to the west, through whose apse the access to the main castle has probably been broken since the 17th century. A room adjacent to the Gothic vault in the south with lancet vaults resting on a central column with belt arches was probably only vaulted in the 17th century when the entire building was increased. The two upper floors were provided with beam ceilings, of which until 1993 essentially only the girder beams had survived. Judging by their profile, the beamed ceilings were pulled in in the 17th century.
After the end of the Second World War , the castle was nationalized and fell into disrepair. It has been privately owned again since 2000. The oldest preserved building in the castle is the Romanesque chapel. Today Wildstein hosts a hotel.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
