Some islands in the world are divided between two different countries. These islands have borders that separate one nation from another while sharing the same landmass. Such islands are geographically unique because they are governed by different governments on the same island. Among all such islands, one island is especially well known for being shared by two countries in the Caribbean region. This island is historically and geographically significant.
