What did Hadrian inspect during his travels through the Roman provinces?

During his extensive travels throughout the Roman provinces, Hadrian primarily focused on inspecting troops and examining frontier defenses to ensure the security of the empire.1

His inspections were characterized by a rigorous approach to military standards. For example, at Lambaesis in Algeria, he conducted a thorough review of the soldiers, maintaining severe standards of discipline that were documented in a surviving address to the troops. Beyond military oversight, his journeys were driven by a deep need for imperial supervision and an insatiable curiosity about the diverse regions and peoples of the empire.1

These travels also led to significant infrastructure projects, most notably the initiation of Hadrian’s Wall in northern Britain, which was designed to control movement across the frontier and counter low-intensity threats.12
