Which emperor is associated with the construction of the Pantheon?

The Pantheon, one of ancient Rome's most iconic and well-preserved buildings, is primarily associated with Emperor Hadrian. Though the structure was initially commissioned by Marcus Agrippa during his time as a consul, it is Hadrian who is credited with its completion and significant reconstruction after the original building was damaged by fire. Under Hadrian's reign, the Pantheon was rebuilt between 118 and 125 AD, with the design that is admired today featuring its grand portico and the massive concrete dome crowned by the oculus.

Hadrian's innovative use of materials and engineering techniques allowed for the creation of the Pantheon's large interior space, which continues to inspire architects and visitors alike. He was heavily influenced by Greek architecture, which is reflected in the temple-like front of the Pantheon, but he also made significant advancements that marked the transition towards Roman architectural practices. This iconic structure remains a testament to Hadrian's vision and leadership in Roman architecture.
