ROME, Sept 3 (Reuters) - The Arch of Constantine, a giant ancient Roman arch next to the Colosseum, was damaged after a violent storm hit Rome, conservation authorities said on Tuesday.

The triumphal arch was built in the fourth century A.D. to celebrate the victory of Constantine — the first Roman emperor to convert to Christianity — over his rival, Maxentius.

Braving bitter cold and wind, archaeologists in Serbia surveyed the site of an ancient Roman triumphal arch, one of only a handful in the Balkans, that dates back to the third century.
