The National Library of Greece is situated near the center of city of Athens. It was designed by the Danish architect Theophil Freiherr von Hansen, as part of his famous Trilogy of neo-classical buildings including the Academy of Athens and the original building of the Athens University. It was founded by Ioannis Kapodistrias. The original idea for establishing a National Library was from the philhellene Johann Jakob Mayer, in an August 1824 article of his newspaper Ellinika Chronika, published at Missolonghi, where Mayer and Lord Byron had been promoting Greece's independence. Mayer's idea was implemented in 1829 by the new Greek government of Ioannis Kapodistrias, who grouped together the National Library with other intellectual institutions such as schools, national museums, and printing houses. These were all placed in a building (then being used as an orphanage) on the island Aegina and supervised by Andreas Moustoxydis, who thus became president of the committee of the Orphanage, director of the National Archaeological Museum of Athens, and director of the National School. At the end of 1830, the library, which Moustoxydis named the National Library, had 1,018 volumes of printed books, which had been collected from Greeks and philhellenes. In 1834, the Library was relocated to Athens, the new capital, and was at first housed temporarily in the public bath in the Roman Agora of Athens and then later in the Panagia Gorgoepikoos church. The collection increased rapidly. In addition to the purchase of books from private libraries, supervised by Dimitris Postolakas (1,995 volumes), the Library accepted many large donations of books, like one from Christoforos and Konstantinos Sakellarios (5,400 volumes) and one from Markos Renieris (3,401 volumes). In 1842, the Public Library merged with Athens University's library (15,000 volumes), and was housed together with the currency collection at the new building of Otto's University. The first director (then-called "president") was Georgios Kozakis-Typaldos of the newly enlarged institution, retaining the job until 1863. At this time, the Library was enriched with significant donations and with rare foreign language books from all over Europe. With the royal charter of 1866, the two libraries merged, and were administered as the "National Library of Greece". From 1877–1910, its director was Michael Deffner. On 16 March 1888 the foundation stone for a new neoclassical marble building was laid. The building was financed by three Kefallonian-born brothers of the Diaspora, Panagis, Marinos and Andreas Vallianos. It was designed by Baron Theophil von Hansen and its construction supervised by Ernst Ziller. The Library remained in the older University building until 1903, when it was relocated to the new Vallianos building, which still partly houses the Library in addition to two other buildings, at Agia Paraskevi and Nea Halkidona.
