The iconostasis, which is mainly found in Eastern churches, is an architectural structure that divides the area of the presbytery from that of the nave. The iconostasis could also display icons, sacred images that had a symbolic role of prominence and connection between God and the faithful. The iconostasis can be set up with columns supporting an architrave. It is therefore a sort of wall that hides the altar from the faithful, marking a spiritual margin between the visible world and the invisible one.
