The construction on Nelahozeves Castle began under the orders of Florian Griesbeck von Griesbach, a Tyrolean aristocrat and adviser to Emperor Ferdinand I, who commissioned the building from royal master builder Bonifaz Wolmut. The castle took more than sixty years to build and was completed at the beginning of the 17th century, more than a decade after Florian's death.
However, financial difficulties forced the von Griesbach family to sell the castle to Polyxena, 1st Princess Lobkowicz (1566-1642), in 1623. The castle was severely damaged during the Thirty Years' War, but was reconstructed by Václav Eusebius, 2nd Prince Lobkowicz (1609-1677), who used the castle as the center for administration and management of his estates.
The castle never served as the Lobkowicz family’s primary residence. In the late 19th and early 20th centuries, it was home to the Order of the Sisters of God's Love, a religious institution for widowed or unmarried noblewomen founded by Princess Wilhelmina Lobkowicz (1863-1945).
Nelahozeves Castle was confiscated by the Communist government in 1948, and housed an exhibition of modern socialist art run by the Czech Regional Gallery in the 1970s and 80s. It was returned to the Lobkowicz family in 1993, and now features an exhibition of historical period rooms, demonstrating the lifestyle of a Bohemian noble family in the mid-19th century. The castle also houses part of the Lobkowicz collection of paintings.
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.
