Hadrian`s Library is located on the north side of the Acropolis of Athens. This majestic structure was built in 132 AD by the Roman emperor Hadrian as part of his grand plan to revive and beautify Athens, which he sought to transform into the cultural capital of the ancient world.
Architecture of Hadrian`s Library
Hadrian`s Library was designed as a typical Roman forum structure — a rectangular building with high surrounding walls and a single monumental entrance. The building had impressive dimensions: 122 meters in length and 82 meters in width. It was a true architectural complex, not just a repository for books. Inside was a spacious peristyle courtyard, in the center of which was a garden and a decorative pool.
West Facade of Hadrian`s Library
The main entrance was on the west side and consisted of a monumental portico in the Corinthian order. On either side of the entrance stood seven columns of green Karystos marble on each side. Above the columns, statues were likely placed against a wall of Pentelic marble. To emphasize the grandeur of the entrance, an area 22 meters wide was cleared in front of the building, creating an impressive square.
Interior and Rooms of Hadrian`s Library
The inner courtyard was surrounded by colonnades of approximately 100 columns. At the corners of the courtyard were exedras, and in the center of each long side were rectangular halls. The main book repository was located in the eastern part of the building, opposite the entrance. There, in special niches in the walls, papyrus scrolls — the "books" of that time — were stored. On either side of the main repository were reading rooms, and at the edges of the wing were lecture halls with amphitheater rows of stone seats.
The Library as a Center of Knowledge
In antiquity, libraries were not public in the modern sense — they served as repositories of documents and places for study and discussion. Hadrian`s Library was the largest in Athens and served several functions:
• Repository of literary works — the most important texts of antiquity were collected here
• State archive — official documents and legal records were stored here alongside books
• Educational center — several philosophical schools were housed in the building and public lectures were held
The traveler and geographer of the 2nd century AD, Pausanias, who visited the library, described it as "a building with 100 columns of Phrygian marble, with rooms with painted ceilings, alabaster walls and niches with statues, in which books were stored." An inscription on the site indicates that the library was open from dawn until noon.
Destruction and Decline
In 267 AD, Athens was invaded by the Germanic tribe of the Heruli. The barbarians looted and burned the city, and Hadrian`s Library was seriously damaged. In 277 AD, as the city sought to better defend itself, the ruins of the library were incorporated into the late Roman defensive walls.
However, the library was not completely abandoned. Between 407 and 412 AD, the prefect of Illyricum, Herculius, restored the building. A statue of Herculius was erected at the entrance, and the dedicatory inscription is still visible on the left side of the entrance.
Three Churches on the Site of Hadrian`s Library
The most remarkable chapter in the history of Hadrian`s Library begins in the Byzantine period. Within the courtyard of the ruins, three churches were successively built.
Tetraconch (5th century): In the mid-5th century, an early Christian church in the form of a tetraconch was erected in the center of the peristyle courtyard — a "four-lobed" building with a square central hall and four semicircular apses on each side. This church, adorned with marble cladding and rich decoration, was associated with the Athenian empress of Byzantium, Eudocia. Unfortunately, it was destroyed at the end of the 6th century.
Three-aisled Basilica (7th century): In the 7th century, a three-aisled basilica was built on the same site, which also did not survive — it was destroyed by a fire in the 11th century.
Megali Panagia (12th century): At the end of the 11th — beginning of the 12th century, a new church was built here, which became the first cathedral of Athens and was known as Megali Panagia. It was smaller, with a single nave. This church survived until 1885, when it burned down in a great fire.
Church of the Archangel Michael: In addition to these three churches, in the 12th century, a small church dedicated to the Archangel Michael was built against the north wall of the library. It was built by the Chalkondili family and used for burials of members of this family. Unfortunately, the church was demolished after 1843.
Ottoman Period and Modern Times
After the Turks captured Athens, the library changed its function once again. It became an administrative center — the residence of the Turkish voivode (governor). Two important bazaars and residential houses were also located on the premises.
In the 18th century, the building served simultaneously as a mosque and a fortress. In 1814, a tower was built here, on which a clock, a gift from Lord Elgin, was later installed. In the 19th century, after the formation of the independent Greek state, barracks for King Otto were established on the site of the voivode`s palace, followed later by a prison.
Archaeological Excavations and Restoration
Excavations at the site of Hadrian`s Library began in the late 19th century, but it was only in the second half of the 20th century that the later buildings were completely cleared and the restoration of the library began.
Today, on the site, one can see the restored west facade — it is preserved sufficiently to give an idea of the scale of the building, part of the east wall where the original niches for storing scrolls are visible, the stone benches of the lecture hall where the supports for the benches and the curved first row of seats are preserved, the ruins of three churches in the central courtyard, including fragments of mosaic floors, as well as the colossal statue of Nike, found here in 1988.
What Tourists Can See Today
Today, Hadrian`s Library is a picturesque ruin located in the historic center of Athens, right behind the Monastiraki metro station.
What has survived:
• The west facade with Corinthian columns — the most impressive part of the ruins. Four columns (out of the original fourteen) have been restored and give an idea of the grandeur of the entrance.
• The Tetraconch church — the well-preserved "four-lobed" 5th-century building in the center of the courtyard. Its unique architecture is clearly visible and accessible for viewing.
• The east wall with niches — here you can see the original niches in which papyrus scrolls were stored.
• The stone benches of the lecture hall — preserved fragments of amphitheater seats where philosophers and orators once were heard.
• Fragments of mosaic floors — remnants of the floor coverings of the Byzantine churches.
Hadrian`s Library is a unique monument that allows one to trace nearly 1,900 years of Athenian history in a single place. Beginning its journey as a majestic center of knowledge in the Roman era, it transformed into an early Christian shrine, then into a Byzantine cathedral, later into an administrative center and fortress of the Ottoman period, and today delights travelers with its picturesque ruins.
