Gotland County (Gotlands län) is a county or län of Sweden. Gotland is located in the Baltic Sea to the east of Öland, and is the largest of Sweden's islands. Counties are usually sub-divided into municipalities, but Gotland County only consists of one municipality: Gotland Municipality. Gotland County is the only county in Sweden that is not governed by a county council. The municipality handles the tasks that are otherwise handled by the county council, mainly health care and public transport. Like other counties, Gotland has a County Administrative Board that oversees implementation of the Swedish state government.
