Kalymnos is an island in the Dodecanese and is located in the southeastern Aegean, just a short distance from Leros, from which it is separated by a strait. Kalymnos is famous for its residents' occupation of sponges, thanks to which there are today three museums and a modern archaeological museum on the island.
In the area of Pothia, the capital of the island, lies the great harbor of Kalymnos. An airport has also been operating in recent years, with daily flights to and from Athens.
Kalymnos has an area of 111.14 sq. Km and has a population of 16,179 inhabitants, according to the 2011 census, making it one of the most populous islands in Greece.
Kalymnos has been inhabited since the Neolithic times. The earliest inhabitants of the island were the Kares, which is evidenced by the Karikian ruins in the ancient metropolis of Kastella, near present-day Stimenia.
Later, the Phoenicians inhabited it, as evidenced by the ruins of Emporio.
The more recent history of Kalymnos was related to the fishing, processing and trading of the sponge.
