The library of Hadrian is among the largest classical monuments in Athens. The Roman Emperor Hadrian constructed the library in 132 AD. The ancient writer Pausanias credited the building as the emperor’s most famous structure and described the one hundred columns of Phrygian marble, the ornate rooms with gilded ceilings, alabaster, paintings, statues, and storage rooms for scrolls of books. The library parallels the classic Roman Forum architectural style externally. The location attempts to unite Greece and Rome. It sits east of the Athenian Agora and north of the Roman Agora. The complex measures about 87 meters by 125 meters within its wall that encased the building. The main entrance is impressive. On either side of the entranceway with fluted Corinthian columns stand seven marble columns from Karystos in Euboea rising on pedestals. Statues stood atop each of the columns.
