Triumphal Arches, popularized by the Ancient Romans, but built in modern times as well, originated as ways to celebrate great victories and great military leaders. A classic example is the Arch of Constantine in Rome.


With the rise of Christianity and the understanding that the greatest victory is Christ’s victory over sin and death, triumphal arches of a very different sort began to be incorporated into Churches.
