Hadrian's Library
Hadrian's Library is the ruin of a monumental building created by Roman Emperor Hadrian in AD 132 on the north side of the Acropolis of Athens.
The main entrance to the library was part of the Stoa of Hadrian with columns of Karystian marble and Pentelic capitals. The library opened to the Roman agora, by a porch and pediment.
The building followed a 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 cupboards and shelves containing rolls of papyrus "books" were kept. Adjoining halls were used as reading rooms, and the corners served as lecture halls.
The ceilings were gilded wood and the walls covered in marble and paintings.
The library was seriously damaged by the Herulian invasion of 267 and repaired by the prefect Herculius in 407–412.
The library was later incorporated into the Roman city walls.
During Byzantine times, three churches were built at the site, the remains of which are preserved:
- a tetraconch
- a three-aisled basilica, and
- a simple cathedral, which was the first cathedral of the city, known as Megali Panagia.
