A lot of times borders and border control between countries can be a complicated and complex matter, especially if there are issues like war, mass immigration, or just plain old conflict between nations. But sometimes, and especially when there is a good, neighbourly relation between countries, borders are merely a formality and give way to some cool places where you can technically be in two places at once.

Whether man-made or natural wonders, we are sure there are at least a few of these borders that will pique your interest. We want to go visit them all (including the last one! lol).
