It is the oldest preserved secular building in Moscow. Located on Kremlin Cathedral Square, between the Cathedral of the Annunciation and the Dormition Cathedral. Currently, it is an official ceremonial hall in the residence of the President of the Russian Federation and thus admission is limited to prearranged tours only.
