Everything Wikidata records in Åland Islands that is a building, a landform, a protected area or a tourist attraction, has coordinates, a photograph and an English Wikipedia article, is ranked by how many Wikipedia language editions wrote about it. Provinces, cities, airports, stations and stretches of sea shared with the neighbours are filtered out.

Swedish. The currency is EUR.

How do I get mobile data in Åland Islands?
