As the imperial court had its seat in Vienna, the Prague palaces ceased to be used for accommodation; their owners moved to follow the court. In the beginning of the 20th century, only a military stable remained in the Schwarzenberg Palace; from 1908, the Schwarzenbergs leased the palace free of charge to the National Technical Museum, which placed its collections on display here. The palace was badly damaged during the May uprising; it was used as an armed central office of the generality. It had to be repaired and after an adaptation, the Museum of Military History opened its first exposition here on the 1st June 1947. The Museum of Military History, founded in 1919, was originally placed in the Černín Palace, and later also in Invalidovna. During occupation, it was annexed by the Nazis and the collections were taken to Germany. Luckily, most exhibits were found and returned to the museum after the war.In the year 2000, the exposition of the Museum of Military History was closed due to reconstruction, which was completed in 2007. Now the palace is owned by the National Gallery, which opened a new exposition here in March 2008, named Bohemian Baroque.
