In Catholic tradition, the Altar of Repose is a significant architectural element serving a specific liturgical function. Located within the sacred space of a church, usually a chapel or side altar, it's a designated area for the reserved Blessed Sacrament after Mass. Its primary purpose is to provide a place of rest and adoration for the consecrated host, typically during the Easter Triduum or other significant feast days. The altar's design and placement emphasize its importance, signifying the continued presence of Christ in the Eucharist and underscoring the reverence due to the sacred host.
