Entrance to the Temple of Romulus (Tempio di Romolo) in the Roman Forum. Built by the Roman Emperor Maxentius (306-312 CE) and dedicated to his son Valerius Romulus who died at age fourteen in 309 CE. The green bronze doors are original, making them about 1700 years old! They survived the sacking of Rome by the Visigoths and numerous other disasters intact.
