Åland Islands

Åland is an autonomous and demilitarised region of Finland. Receiving its autonomy by a 1920 decision of the League of Nations, it is the smallest region of Finland by both area and population, constituting 0.51% of Finland's land area and 0.54% of its population. Its only official language is Swedish and the capital city is Mariehamn.

Åland is situated in a Finnish archipelago, called the Åland Islands, at the entrance to the Gulf of Bothnia in the Baltic Sea. It comprises Fasta Åland, on which 90% of the population resides, and about 6,500 skerries and islands to its east, of which about 60–80 are inhabited. Fasta Åland is separated from the coast of Roslagen in Sweden by 38 kilometres of open water to the west.
