The Iconostasis
The most conspicuous characteristic of an Orthodox church is the Iconostasis, consisting of single or more rows of Icons and fragmented near a set down of doors in the center (the Sacred Doors) and a door at each side (the Deacons Doors). In old times, the Iconostasis was likely a partition placed at the extreme Eastern extremity of the church (a custom quiet preserved near Russian Elderly-Believers), but quite beforehand it was moved outside from the screen as a kind of bar between the Nave and the Altar, with the break and closing of curtains making the Altar both seeable and inaccessible.
Sacred Fathers envisioned the church edifice as consisting of three allegorical parts. According to Patriarch Germanus of Constantinople, a Confessor of Orthodoxy during the iconoclastic controversies (7th-8th Centuries), the church is the earthly paradise where Deity, Who is overhead heaven, dwells and abides, and it is more illustrious than the [Old Testament] tabernacle of observer. It is foreshadowed in the Patriarchs, is based on the Apostles…, it is foretold near the Prophets, adorned near the Hierarchs, sanctified near the Martyrs, and its tall Altar stands solidly founded on their sacred remains…. So, according to St. Simeon the Novel Theologian, the [Vestibule] corresponds to earth, the [Nave] to paradise, and the holy [Altar] to what is overhead paradise [Volume on the House of God, Ch. 12].
