The Iconostasis As Icon Wall

An iconostasis is a wall or screen covered in icons that fully separates the sanctuary, where the altar stands, from the nave in an Eastern Orthodox church, replacing the partial screens or rood screens found in Western church traditions with a solid, floor-to-near-ceiling barrier organized entirely around a fixed program of sacred images.

The arrangement of icons on a fully developed iconostasis follows a standardized order rather than an arbitrary decorative scheme: the Royal Doors at the center, through which only clergy pass, are flanked by icons of Christ and the Theotokos, with additional tiers above typically presenting the twelve great feasts of the liturgical year, the apostles, and often the Old Testament prophets, so that the entire structure functions as a theologically organized visual summary of salvation history standing between the congregation and the altar. Rather than concealing the sanctuary from the congregation in the sense of hiding it, Orthodox theology understands the iconostasis as revealing the sanctuary through sanctified image, the icons functioning as windows onto the sacred reality taking place beyond the screen rather than as an obstruction blocking it from view, a framing that distinguishes the iconostasis conceptually from a simple opaque partition wall.
