Acropolis was named as one of the 20 most beautiful World Heritage Sites according to CNN. On the Acropolis, CNN notes, “Looming over the city of Athens, this ancient Grecian citadel was built in the 5th century BC and continually beautified throughout the years by the city’s well-moneyed citizens. Despite being attacked and pillaged by everyone from the Byzantines, who converted the temples into churches, to the Venetians, who later shelled the area, the site still stands to provide an important insight into Greek mythology.”
