Municipal House (Obecní dům) is a civic building that houses Smetana Hall, a celebrated concert venue, in Prague. The Royal Court palace used to be located on the site of the Municipal House. From 1383 until 1485 the King of Bohemia lived in the property. After 1485, it was abandoned. It was demolished in the early 20th century. Construction of the current building started in 1905 and it opened in 1912. The building was designed by Osvald Polívka and Antonín Balšánek. The Municipal House was the location of the Czechoslovak declaration of independence.
The building is of the Art Nouveau architecture style. The building exterior has allegorical art and stucco. There is a mosaic called Homage to Prague by Karel Špillar over the entrance. On either side are allegorical sculpture groups representing The Degradation of the People and The Resurrection of the People by Ladislav Šaloun. Smetana Hall serves as a concert hall and ballroom. It has a glass dome. There is artwork by Alfons Mucha, Jan Preisler and Max Švabinský, too.
Today, the building is used as concert hall, ballroom, civic building, and as the location of cafes and restaurants. Many of the rooms in the building are closed to the public and open only for guided tours.
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.
