Not only do borders define us, but they also determine who we are. Simple lines on the ground, either man-made or geological, distinguish one culture from the next.
Country borders are frequently some of the most battled over and closely defended areas on the planet.
Below is a list of some of the Coolest and unique international borders you must see.
1. United States and Mexico

To help curb illegal immigration, US border patrol has kept its area on the Mexican border [right]. Regardless, the border between the two countries is one of the most heavily visited in the world, spanning about 3200 kilometers.
2. Netherlands and Belgium

The town of Baarle, which is located directly on the line separating the Netherlands [left] from Belgium [right], is possibly the most charming border on the list. Why not have tea in one country and eat a pastry in the other?
3. North Korea and South Korea

This is possibly one of the most closely guarded borders on the list, as it is located within the demilitarized zone between the two countries. In reality, the two countries are still formally at war, with American forces stationed on the South Korean side to this day.
One of the world’s most dangerous and tense border crossings. Members of both militaries are continually guarding it. An international border incident here would not be a smart idea because it wouldn’t take much to set this entire region on fire.
4. Argentina, Brazil, and Paraguay

South America is a stunning wilderness with rushing rivers aplenty, the most famous of these was the Amazon. Many countries are divided by the water’s edge since water runs all over the continent. for example, the fork in the river where Argentina, Brazil, and Paraguay all connect.
5. Slovakia, Austria, and Hungary.

Do you want to eat lunch in three different nations at the same time? You can do it right here, and they’ve even set up a picnic table to make it possible. They don’t bother about guards or walls since the border between these three countries is so porous that they can sit down and enjoy a pleasant lunch with anybody they choose.
6. Germany and Poland.

This would not have been conceivable a few decades ago, but as Europe has evolved, borders have become less stressful areas. Take a stroll along the wooden boardwalk that connects the two countries.
7. Norway and Sweden

The deforested line that separates Norway and Sweden makes for an excellent snowmobiling course.
8. Egypt and Israel

Even from space, the border between Egypt [left] and Israel [right] is clearly visible, despite being an imaginary line drawn in recent history. Canadian Astronaut Commander Chris Hadfield took the photo above while aboard the International Space Station. It’s mind-boggling to consider how much a single line can influence geographical growth and land use.
