In Catholic tradition, the Holy Door is a significant architectural element, typically located in a church's façade or a major wall. Its primary liturgical function is to be opened only during a Jubilee Year, a special period of grace and forgiveness. The act of opening the Holy Door marks the commencement of the Jubilee, transforming the entrance into a symbolic gateway to a sacred space. Passing through this door signifies entering into a period of spiritual renewal and receiving plenary indulgence. Its placement and opening hold deep symbolic meaning, representing the threshold to God's mercy and the forgiveness offered during this sacred time within the Catholic Church.
