In Catholic Church architecture, the presbytery is a crucial architectural element, the raised area encompassing the altar and seating for the clergy. Its primary liturgical function is to house the celebration of the Eucharist and other liturgical rites. Located at the eastern end of the nave, it marks the heart of the sacred space, visually separating the clergy from the congregation. The elevated position reinforces the presbytery's significance within Catholic tradition, symbolically representing the sacredness of the altar and the holy actions performed there. Its very existence emphasizes the importance of the liturgical action within the church building.
