Agathonisi in the context of "Above mean sea level"

The Dodecanese (UK: /ˌdoʊdɪkəˈniːz/, US: /doʊˌdɛkəˈniːz/; Greek: Δωδεκάνησα, Dodekánisa [ðoðeˈkanisa], lit. 'twelve islands') are a group of 15 larger and 150 smaller Greek islands in the southeastern Aegean Sea and Eastern Mediterranean, off the coast of Anatolia, of which 26 are inhabited. This island group generally defines the eastern limit of the Sea of Crete. They belong to the wider Southern Sporades island group.

Rhodes has been the area's dominant island since antiquity. Of the others, Kos and Patmos are historically the most important; the remaining 12 are Agathonisi, Astypalaia, Halki, Kalymnos, Karpathos, Kasos, Leipsoi, Leros, Nisyros, Symi, Tilos, and Megisti. Other islands in the chain include Alimia, Arkoi, Farmakonisi, Gyali, Kinaros, Levitha, Marathos, Nimos, Pserimos, Saria, Strongyli and Syrna.

Arkoi (Greek: Αρκοί; also Arkioi (Αρκιοί)) is a small Greek island in the Dodecanese archipelago, located east of Patmos, north of Leipsoi and southwest of Agathonisi. The island belongs to the municipality of Patmos, which is part of the South Aegean region, and had a population of 54 inhabitants at the 2001 census.

The small population means that there is no real capital, but most inhabitants live close to the main harbour with the rest living scattered around the island on higher ground. The majority of the population finds employment in fishing, merchant shipping, goat herding or running one of the island's four tavernas.

Farmakonisi (Greek: Φαρμακονήσι) is a small Greek island and community of the Dodecanese, in the Aegean Sea, Greece. It lies in the middle between the chain of the Dodecanese islands in the west, and the coast of Asia Minor (Turkey) in the east. To the north of it are the island of Agathonisi, to the west the islands of Leipsoi, Patmos and Leros, and to the south the islands of Kalymnos and Pserimos. It forms part of the municipality of Leros, and had at the 2021 census a population of 21 inhabitants. Prominent historical monuments on the island include the church of Agios Georgios (Greek: Άγιος Γεώργιος) and the nearby ruins of an ancient Roman temple.

The area of Farmakonisi is 1.48 sq mi (3.8 km).

Kalymnos (Greek: Περιφερειακή ενότητα Καλύμνου) is one of the regional units of Greece. It is part of the region of South Aegean. The regional unit covers the islands of Kalymnos, Agathonisi, Astypalaia, Leipsoi, Leros, Patmos and several smaller islands in the Aegean Sea.
