Definition: Ante-chor, in Greek, refers to a structure or part of a building where a roof extends over a main entrance; itβs often used as a decorative feature around windows or openings at the top of buildings. Its importance varies based on architectural style and function within the building. In general, an ante-chor is usually found inside a cathedral, church hall, or other high-ceilinged spaces where a roof provides additional space for prayer.
