The main building of the French School in Athens, one of the seventeen foreign archaeological institutes operating in the capital city, was declared a monument by the Central Council of Modern Monuments. The neoclassical building of the French school was built in 1872-1873 and houses a library, offices, a conference hall, and the director's residence.

The Committe decided unanimously to declare only the main building a monument, given that the other, smaller buildings have undergone a series of interventions throughout the years, and only the main building has maintained its authentic character entirely.

Its preservation was also considered important for the study of the development of Athens' architecture, and of the history of French philhellinisn the 19th century.
