The National Library of Greece is situated in the centre of the 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 consists of three solid parts, out of which the one in the middle, which is also the biggest, houses the Reading-Room. To enter this part, one has to pass through a Doric-style row of columns (designed after the Temple of Hephaestus in the Ancient Agora of Thisseion, which served as its model), after climbing on a monumental curved double staircase of a Renascence style. The Reading-Room, surrounded by Ionian-style columns, is covered by a glass ceiling. The cast-iron constructions of the bookstands were referred to as exceptional back in their time. In general, the building is considered to be a characteristic sample of mature Neoclassicism.
