Hadrian’s Villa. Hadrian was one of Rome’s most benevolent emperors, ruling from 117-138 AD. His villa showed he was also one of the richest. Here we are posing at the Canopo, his 120-meter-long pool, and inside his, ahem, quaint little bath house. It’s one of the most well-preserved Roman ruins in the world and when you have it almost to yourselves, you really do feel like royalty.
