On the site of the present Krásné Březno chateau there used to stand a farmhouse with a fort. Until 1867, the name of the village was Březnice, before, it was called Březník. The first written mention of it is in the deed of Prince Spytihněv II dated 1057. Before 1600, he had a Renaissance chateau built instead of the original fort of Rudolf of Býnov. The builder was Hans Bog of Pirna. On the old wing’s facade, connected to the chateau church of St. Florian by a corridor, there is a sun dial showing the date 1603 and the Latin inscription Soli deo Gloria. In 1730, the chateau was rebuilt in the Baroque style by Ludvík Richard Cavriani. In the 19th century, the building was extended with a new wing with a balcony.
At the moment, the chateau is owned by the National Heritage Authority in Ústí nad Labem, which is preparing an extensive reconstruction project of the chateau. It is to seat the heritage authority, however, it shall also boast representative rooms that shall be available to the public.
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.
