Belgium - Netherlands
Baarle-Hertog is an iconic municipality in Belgium. It's notoriety comes from its complicated borders with Baarle-Nassau, another city in the Netherlands. This region comprehends a total of 24 separate parcels of land, none of which is contiguous with the rest of each country.
The jumble of white crosses marks the intertwined towns of Baarle-Hertog and Baarle-Nassau. This peculiar border was created after a treaty in 1843.
Mexico - United States
One might think that after all the political conflicts between these two countries, the border would be clear and very protected. However, on the border between San Diego and Tijuana you'll find a pretty interesting mix of cultures.
This boarder has walls, fences and three checkpoints. Nevertheless, it is really common for people to get together and talk freely through the fence.
Argentina - Brazil
