Gennadius Library

The Gennadius Library, also known as the Gennadeion, is one of the most important libraries in Greece, with over 110,000 volumes on Greek history, literature and art from Antiquity until modern times. The library is located at Souidias Street 61, on the slopes of Mount Lycabettus, in central Athens.

The library is one of the two belonging to the American School of Classical Studies at Athens. Its core founder was the Greek diplomat Joannes Gennadius, who initially donated part of his collection to the newly founded National Library of Greece. Returning to Athens a few years later he was distraught to discover they had no reference to his donated items, and so he resolved to find a better home for his collection. While attending the Washington Naval Treaty, American scholars showed interest in founding a dedicated facility in Greece.
