The nave of the church is separated from the sanctuary by a screen called the iconostas, in Serbian ikonostas. It is a tall partition made of carved wood. In the icononstas, there are three doors leading into the sanctuary. The middle door has two wings called the royal doors, in Serbian carske dveri. Through these doors our Lord Jesus Christ, the King of Kings, passes in the myster of the Holy Communion. Symbolically, the royal doors represent the portals of the Kingdom of Heaven.

A layman is never allowed to pass through them; only clergy in their vestments may enter through the doors. A curtain, made of red velvet, hangs inside the sanctuary above the royal doors. It slides and may be drawn as needed. This curtain signifies the curtain of the Holy of the Holies in the temple of the Old Testament.

The door on the left side of the royal doors leads into the northern section of the sanctuary, where the sacrificial table stands, and the door on the right side leads into the southern section of the sanctuary called the sacristy.

The side of the iconostas facing the nave is adorned with holy icons which are arranged in a prescribed liturgical order.

Painted on the wings of the royal doors is the icon of the Annunciation to the Most Holy Virgin Mary. Half of this icon is painted on one wing and half on the other. The four Evangelists are painted in respective corners of this icon. Symbolically, this icon indicates how the Most Holy Virgin Mary, according to the Evangelists, became the door through which Salvation came to mankind.

On the right side of the royal doors the icon of Jesus Christ is represented, and on the left side is the icon of the Mother of God with the Infant Jesus. These two icons are called throne icons, in Serbian prestone ikone. On the side doors of the iconostas are icons of Saint Stephen the Archdeacon and that of Saint Archangel Michael.

On the right side of the door leading into the sacristy stands the figure of Saint John the Forerunner and the icon of the Venerable Mother Paraskeva and martyr Tryphon. On the left side of the door leading into the northern section of the sanctuary is the icon of Saint Sava, patron saint of the church, with Saints Nicholas and George.

Over the royal doors is the representation of the Last Supper, indicating that the Holy Eucharist is celebrated inside the sanctuary. Above the Last Supper icons are images of twelve major feasts representing the twelve great holidays from the lives of our Lord and Mother of God. They are, from left to right: Nativity of the Theotokos, Entrance of the Theotokos into the Temple, Meeting of the Lord, Transfiguration, Epiphany, Nativity of Jesus Christ, Resurrection, Palm Sunday, Lazarus Saturday, Ascension, Pentecost, Assumption of the Theotokos.

All of the above mentioned icons must be represented on every iconostas. In front of each of these icons (except the icons on the side doors) a vigil lamp hangs from above. The iconostas is surmounted by a cross with the image of the Crucified Christ on it.
