Hadrian's Library was created by Roman Emperor Hadrian in AD 132 on the north side of the Acropolis of Athens.The building followed a typical Roman forum architectural style, having only one entrance with a propylon of Corinthian order, a high surrounding wall with protruding niches at its long sides, an inner courtyard surrounded by columns and a decorative oblong pool in the middle. The library was on the eastern side where rolls of papyrus "books" were kept. Adjoining halls were used as reading rooms, and the corners served as lecture halls.
The library was seriously damaged by the Herulian invasion of 267 and repaired by the prefect Herculius in AD 407–412. During Byzantine times, three churches were built at the site, the remains of which are preserved:
