The Church of the Twelve Apostles, distinguished by its 5 beautiful domes, was a private space reserved for the Patriarchs. It was embellished by a remarkable, ornately decorated wooden wall, which unfortunately has not been preserved, but has been replaced by another from the nearby Cathedral of the Ascension, dating from the 1700s. In the church you’ll find various precious icons and Russian masterpieces from the 1600s, many of which were made in the Kremlin workshops.
