Piazza del Collesseo

Triumphal arch decorated with fragments from older Roman monuments, erected in AD 315 in honor of Constantine's victory over Maxentius at the Milvian Bridge.  At this battle in the year 312 Constantine is said to have seen a cross in the sky, bringing about his conversion to Christianity.  The relief work on the inside of the arch depicts the emperor Trajan’s victory over the Dacians in the 2nd century.
