The Acropolis Restoration Service (YSMA) is a special peripheral service of the Ministry of Culture. It was established by the Presidential Edict 97/1999 (Φ.Ε.Κ. 104/Α/26.5.99) in order to organize and carry out the works of conservation and restoration on the Acropolis. Academic responsibility for carrying out the works has, since 1975, been held by the Committee for the Conservation of the Acropolis Monuments (ESMA), an interdisciplinary committee of specialist scholars.
