Entering the Kremlin via Trinity Gate, this is the first building in the Kremlin which tourists can actually get inside. The palace is complemented by the Cathedral of the Twelve Apostles. The two buildings form one structure linked by an arch. The Patriarch is the head of the Russian Orthodox Church; not long after the construction of this building the church was irrevocably split by the reforms of Patriarch Nikon. The building currently contains the Museum of Seventeenth Century Russian Applied Art featuring a host of exhibits, from household items to religious paraphernalia.
