While the Second World War was raging, Brazil and Uruguay did things a little differently. The Uruguayan border town of Rivera butts up against the Brazilian border town of Santana do Livramento and is only separated by a single street.
In commemorating the perpetual peace and mutual trade between the two international towns, the “Plaza Internacional Rivera-Livramento” was built in 1943 and is the only square on earth maintained, administered, and shared by the two countries. The square, while having a dotted border line running through it, is not meant to serve as a border post, and citizens are free to move within it.
The highest point in the Netherlands also serves as a tripoint for the Netherlands, Belgium, and Germany. In an almost similar fashion to other locations in Europe, the tripoint has seen a succession of different territories cross through it due to territorial disputes.
The remains of this history are still evident from the “Viergrenzenweg,” Dutch for “Four Borders Road.” The Four Borders Road refers to the inclusion of the now-extinct territory of Moresnet, which formed an independent condominium for over a century.
The Fence of Gibraltar
England and Spain are separated by over a thousand miles, with Andorra, France, and the English Channel between them. How is it then that the two nations share a border? Successive wars in middle-aged Europe eventually led to a concession by Spain to give a tiny chunk of land to England in 1713, making it a British Overseas Territory on mainland Spain.
The border became extra complicated when Britain decided to abandon the European Union. A treaty was signed that allows for Gibraltar to fall under Schengen rules, which means crossings between the Territory and Spain remain unhindered for citizens
Eastern Upper Lusatia Tripoint
A very picturesque mountain range known as the Sudeten Mountains stretches across and is shared by the three European countries of Germany, Poland, and the Czech Republic. On the western hills of the Sudetes lies the area of Eastern Upper Lusatia, and it is here that the three countries find their borders in a tripoint.
Though the location and nature around it are breathtaking, this tripoint is not one of the more glamorous. Three medium-sized flags just stick out of the ground alongside the riverbank, with a European Union flag thrown in for good measure.
The Karawanken Mountain Border
The Alps have helped Europe settle its border disputes for millennia. The mountain range forms a ridge almost eight hundred miles long and counts Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland among its citizenry. The particular portion of the Karawanken range that runs along the border between Austria and Slovenia, is noted for being particularly treacherous. It has only one road crossing.
The governments of Austria and Slovenia undertook to build a tunnel through the Karawanken, and the Karawaks Tunnel was opened in 1991. The countries are both in the Schengen territory, so no border checks are needed.
