The apse, a semi-circular architectural element found in Catholic churches, holds a significant liturgical function. Located at the eastern end of the building, it typically houses the altar, signifying its central role in the sacred space. This positioning reflects the Catholic tradition of orienting the church eastward, towards the rising sun and the promised land. Its curved shape creates a focal point, drawing worshippers' attention to the altar and the celebration of the Eucharist. The apse's design contributes to the overall sense of awe and reverence within the church building, enhancing the spiritual experience.
