Greece contains the administrative territorial entity monastic community of Mount Athos
Administrative divisions
Since the Kallikratis programme reform entered into effect on 1 January 2011, Greece has consisted of 13 regions subdivided into a total of 325, from 2019 332 (Kleisthenis I Programme), municipalities. The 54 old prefectures and prefecture-level administrations have been largely retained as sub-units of the regions. Seven decentralised administrations group one to three regions for administrative purposes on a regional basis. There is also one autonomous area, Mount Athos (Greek: Agio Oros, "Holy Mountain"), which borders the region of Central Macedonia.
