The Athens Concert Hall Organization, founded in 1981, is a non-profit-making organization administered by a board of trustees, half of whose members are appointed by the Ministry of Culture, Education and Religious Affairs, and half by the Friends of Music – also a non-profit-making charitable association.  The Concert Hall is a creative arena for cultural and educational activities, an arts centre organized along contemporary lines to promote the role of culture in the community. It offers an excellent example of successful collaboration between the state and the private sector.    

Onassis Cultural Centre, part of the Onassis Foundation, is a cultural space hosting events and actions across the whole spectrum of the arts from theatre, dance, music, cinema and the visual arts to the written word, with an emphasis on contemporary cultural expression, on supporting Greek artists, on cultivating international collaborations and on educating children and people of all ages through life-long learning.

The Book Arcade was founded in June 1996 by the Society for the Promotion of Education and Learning (Filekpedeftiki Eteria). It is an attempt to create a Cultural Centre in Athens, as a contribution to detecting and reconciling via books, the greatest ideas of the past, present and future.   The Book Arcade is located in Arsakeio Megaro (Hall).  The Hall is designed and carries a strict classical architectural style with a simplistic decor. It was built based on the architectural design of Lysander Kaftantzoglou (1811-1885) Architect and was the home of the Arsakeio group of schools.

The School was founded in 1881 by a consortium of nine American universities in collaboration with leading businessmen. Built on land deeded by the Greek government, it was the first American overseas research center, and is now the largest, along with the American Academy in Rome. It is the largest of the fourteen foreign institutes located in Athens.

Harokopio University was the 18th University to be established in Greece, upon the initiative of Professor George Karabatzos. The  University bears the name of the national benefactor Panayi Charokopou, a European -minded cosmopolitan, who envisioned an educational institution with excellent building facilities and equipment, operating in harmony with the natural environment, which would provide for a contemporary science learning environment.
