This Baroque palace was named after its last aristocratic owners, the Gallas (later Clam-Gallas) family. General Matthias Gallas acquired the palace in 1634 as confiscated goods after helping to organize the assassination of the powerful military leader Albrecht von Wallenstein and his officers, including the palace's original owner. In 1713 European leading baroque architect Johann Bernhard Fischer von Erlach was charged with refurbishing the palace in the then fashionable High Baroque style, with statuary created by Matthias Bernard Braun. During the 19th and early 20th centuries the palace was put to a variety of uses: as offices, apartments and, at one point, to store hay. From 1945 onwards it housed the Prague City Archives, part of which is still located in the palace. Today, this monumental late baroque aristocratic residence belongs to the City of Prague and cooperates with other organizations in organizing various social and cultural events, as well as exhibitions and conferences.
