During the early 4th century, Constantine I and Maxentius clashed to determine who would be the sole Roman emperor. The conflict was resolved in October of 312 during the Battle of the Milvian Bridge. As promised to Constantine in a vision from God, his troops were victorious and Maxentius drowned in the Tiber River. Three years later, this Arch of Constantine was erected near the Colosseum at Via Triumphalis. Historians believe many of the carvings date back to the middle of the first century during the reign of Hadrian. The triumphal arch measures 69 feet tall and 85 feet wide.
