The nave, a central architectural element in Catholic church architecture, forms the main body of the building. Its primary liturgical function is to house the congregation during services. Located between the entrance and the sanctuary, the nave's expansive space facilitates communal worship within the sacred space. In Catholic tradition, its size reflects the importance of the gathered faithful, visually emphasizing their participation in the liturgy. The nave’s design, often emphasizing length and height, guides the eyes towards the altar, signifying the focus of the sacred act.
