Perhaps the single most unique borders belong to this nation. With over 4000 KM of in length this nation is longer than the US is wide. This is a latin nation that has felt massive influence from Spain, the US, and many of its neighbors. Despite a lot of this influence this land has had a unique culture defined by the indigenous Mapuche people and the modern residents. This nation has held a prideful warrior culture, a powerful mercantile system and a period of rapid development. This is truly one of my favorite nations in the world, this is Chile.
