Centre place above the monastery complex is the Church of the Birth of the Mother of God, with the patron's inscription of Ivan Crnojević engraved on a plaque above the entrance and the coat of arms of Crnojević in the middle of the apse. In addition to the iconostasis of Greek workmanship, the church treasures one of the greatest Montenegrin relics – the relic case of St. Peter, whose cult is respected to such an extent that Cetinje Monastery is also called the Monastery of St. Peter of Cetinje. The graves of Prince Danilo I and Grand Duke Mirko Petrović, his uncle and King Nikola I's father are located here, while in the churchyard are the graves of Darinka and Olga, wife and daughter of Prince Danilo I, Bishop Savo Petrović and Metropolitan Mitrofan Ban. The palace cemetery (added at the end of the 19th century) is where members of Nikola I Petrovic's family were buried. On the south side of the church, there is a two-floor administrative building, with a dungeon in the ground floor, named Guvernadurica, after its the most famous prisoner, Governor Radonjić. The metropolitan's residence, so-called "Njegoš's Konak", includes the monastery treasury. A gumno (threshing floor) in front of the monastery is a more recent reconstruction of the original gumno built by Bishop Sava, according to the dimensions of the Kremlin's Tsar-bell.
