Lysá nad Labem was firstly mentioned in the Chronica Boemorum, with its existence mentioned in 1034. In the 13th century, a castle was built here and until the reign of the Luxembourgs, the town was property of the Czech queens. Since 1291, there has been evidence of Lysá being a town. In that year, Queen Judith of Habsburg issued a charter to unite the settlements of the Lysá estate into one economic unit.
During the Hussite Wars the town suffered a lot. At the turn of the 15th and 16th century, the Smiřický family of Smiřice rebuilt the dilapidated castle into a late-Gothic castle. In 1548, Emperor Ferdinand I added Lysá to the intimate dominion as a hunting centre. After a large fire, he had the castle rebuilt in the Renaissance style.
The sustainable development of the town was stopped by the Thirty Years' War. In 1647, Lysá was acquired by the empire general Johann von Sporck and then the town began to flourish. After the general's death, his son Franz Anton von Sporck began to reign. He made the most important changes in 1696 when the Augustinian monastery was restored and the new parish church and the Chapel of Three Kings were built.
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.
