Ponte Milvio

This guide to Ponte Milvio in Rome opens on the morning of October 28, 312, as two Roman emperors and their armies converge on this four-centuries-old bridge over the Tiber. It follows the vision Constantine described the night before the battle and the sign he had painted onto every soldier's shield, and Maxentius's six years ruling Rome before he rode out to meet his rival here. Stand at the bridge's center and look down at the water below.
