Kytö is an islan in Espoo, Finland. It is one of Espoo's southernmost islands, and beyond it lies mostly only open sea. For decades, Kytö was used by the Finnish Defence Forces as a private training ground, and admittance to it was severely restricted. However, in the early 2000s, the Defence Forces abandoned use of the island, and since then there has been discussion about who really owns the island. Three parties have claimed it as their property: the Defence Forces, the City of Espoo, and a private family who claims that their ancestors owned the island already in the 19th century.
