Gotland is a large Swedish island and province in the Baltic Sea that, until now, has been regarded as a tourist attraction. From a military viewpoint, it occupies a strategic location in the Baltic Sea, so that the growing threat from Moscow and Sweden’s entry into NATO are turning this Scandinavian outpost into an ‘unsinkable aircraft carrier in the Baltic’. The biggest town, Visby, is distinguished by its cobblestone streets and well-preserved medieval city wall, and is also home to the grand, centuries-old St. Mary’s Cathedral. ‘Gotlands Museum’ traces the island’s natural and cultural history with art and artifacts. Gotland is a fully integrated part of Sweden with no particular autonomy, and the archipelago today is a very popular domestic tourist destination for mainland Swedes, thanks to the sunny climate and the extensive shoreline on mild water. Also, during summer Visby hosts the political event Almedalen Week followed by the Medieval Week. In winter, Gotland usually remains surrounded by ice-free water and has mild weather. Gotland’s location in the centre of the Baltic Sea has historically given it great strategic importance. Nowadays the island’s main sources of income are agriculture, food processing, tourism, information technology services, design, and some heavy industry such as concrete production from locally mined limestone.
