Built between 1755 and 1765 by Anselmo Lurago according to the designs by Kilian Ignaz Dientzenhofer, it is the most beautiful Rococo building in Prague. In 1768 it was bought by Stepan Kinsky, an Imperial diplomat. In February 1948 Klement Gottwald proclaimed communist rule in Czechoslovakia from the palace balcony. Nowadays, the Kinsky Palace belongs to the National Gallery.
