A fun example of an island which is not disputed: Märket is a small uninhabited island located between Sweden and Finland. It&#x27;s divided between the countries and Finland even built a lighthouse on the wrong side of the border!<p>Another example i the island Kataja, which didn&#x27;t even exist when the border between Sweden and Finland was drawn, but now sits on the border.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;M%C3%A4rket" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;M%C3%A4rket</a>
