Chinese workers in front of a replica colosseum, built during the reign of the Roman emperors Vespasian and Titus.
And although most of that has been original infrastructure, China also focused its attention on building replicas of world-famous tourist destinations.
Many of the original "world wonders" are considered cultural status symbols that reflected an empire's soft power. Consequently, some analysts believe that it's about more than just pretty tourist spots for China.
"The ancient parallels for these copycat projects suggest that they are not mere follies, but monumental assertions of China's global primacy," Oxford University scholar and archaeologist Jack Carlson wrote a few years back.
