Kalymnos (regional unit) in the context of "Kalymnos"

Patmos (Greek: Πάτμος, pronounced [ˈpatmos]) is a Greek island in the Aegean Sea. It is famous as the place where, according to Christian belief, John of Patmos received the vision found in the Book of Revelation of the New Testament, and where the book was written.

One of the northernmost islands of the Dodecanese complex, Patmos has a population of 3,283 (2021) and an area of 34.05 km (13.15 sq mi). The highest point is Profitis Ilias, 269 metres (883 ft) above sea level. The municipality of Patmos, which includes the offshore islands of Arkoi (pop. 44), Marathos (pop. 5), and several uninhabited islets, has a population of 3,047 (2011 census) and a combined land area of 45.039 square kilometres (17.390 sq mi). It is part of the Kalymnos regional unit.

Astypalaia (Greek: Αστυπάλαια, pronounced [astiˈpalea]), is a Greek island with 1,376 residents (2021 census). It belongs to the Dodecanese, an archipelago of fifteen major islands in the southeastern Aegean Sea. However, many scholars recognize Astypalaia as an extension of the Cyclades, as many cultural and ecological components of the island are more indicative of the Cyclades rather than the Dodecanese.

The island is 18 kilometres (11 miles) long, 13 kilometres (8 miles) across at its widest, and covers an area of 97 km. Along with numerous smaller uninhabited offshore islets (the largest of which are Sýrna and Ofidoussa), it forms the Municipality of Astypalaia, which is part of the Kalymnos regional unit. The municipality has an area of 114.077 km. The capital and the previous main harbour of the island is Astypalaia or Chora, as it is called by the locals.

Leipsoi (Greek: Λειψοί [lipˈsi]; also: Lipsi; Ancient Greek: Λέψια, Lepsia) is an island south of Samos and to the north of Leros in Greece. It is well served with ferries passing between Patmos and Leros and on the main route for ferries from Piraeus. Leipsoi is a small group of islets at the northern part of the Dodecanese near Patmos island and Leros. The larger Leipsi-Arkoi archipelago consists of some 37 islands and islets of which only three are larger than 1 square kilometre (247 acres): Leipsoi (15.95 square kilometres (6.16 sq mi)), Arkoi (6.7 square kilometres (2.59 sq mi), part of Patmos municipality) and Agreloussa (1.32 square kilometres (0.51 sq mi), part of Patmos municipality). Only Leipsoi, Arkoi, and Marathos are inhabited. Leipsoi is a municipality, part of the Kalymnos regional unit, which is part of the South Aegean region. The municipality has an area of 17.350 square kilometres (6.699 sq mi). In ancient times, it contained a town named Lepsia.

Leros (Greek: Λέρος), also called Lero (from the Italian language), is a Greek island and municipality in the Dodecanese in the southern Aegean Sea. It lies 317 kilometres (197 miles; 171 nautical miles) from Athens's port of Piraeus, from which it can be reached by a nine-hour ferry ride or by a 45-minute flight from Athens.
