Netherlands and Belgium
What is perhaps the quaintest of borders on the list, the town of Baarle sits just on the line marking the Netherlands [left] from Belgium [right].
Norway and Sweden
Argentina and Brazil
The Iguazu Falls vary from 60 to 80 meters high but partially sit along the border of Argentina and Brazil.
United States and Mexico
USA border protection has kept their land on the border of Mexico [right] fairly barren in order to help stop illegal immigration.
Afghanistan and Pakistan
Italy and Switzerland
Along the border of Italy and Switzerland high up in the alps sits a single hut used as a research center for low temperature climates. The unique building can only be reached by foot and was first constructed by the Queen of Italy in 1893.
Egypt and Israel
While simply an imaginary line decided upon in recent history, the border between Egypt [left] and Israel [right] is clearly seen even from space.
Nepal and China
Mount Everest sits right on the border of Nepal and China making it one of the highest international borders that exists.
Spain and Morocco
Much like the Mexican-American border, Spain erected a long fence in order to keep illegal immigrants traveling through Morocco out of the country.
North Korea and South Korea
Located within the de-militarized zone between the two countries, this is possibly one of the most heavily guarded borders on the list.
