What was Emperor Hadrian's most prominent contribution to the Age of the Five Good Emperors?

Question

Quizplus · Accepted Answer

Emperor Hadrian's most prominent contribution was his focus on fortifying and securing the Roman frontiers. He is most famously known for building Hadrian's Wall in England, which helped to protect the empire from invading tribes. Through his military campaigns and defensive structures, Hadrian helped to maintain the stability and security of the empire during his reign. The other choices are not accurate, as Hadrian did not conquer Armenia and Assyria, did not build the Roman Colosseum (it was built before his reign), and did not rebuild Rome after a major fire during his reign (that was the work of Emperor Nero).
