5Archeological site of Leptis Magna, Libya

Libya is home to five UNESCO World Heritage sites, including the remarkably preserved remains of Leptis Magna — described by the organization as “one of the most beautiful cities of the Roman Empire.”

While Leptis Magna is full of large, spectacular structures, including a racecourse measuring 1,500 feet in length, and a vast amphitheatre built by the Romans between the first and third centuries AD, it was abandoned in the seventh century and got buried under layers of sand until the site was excavated in the early 20th century.
