Tri-border region
A triangle - also known as a country triangle - is the geographical point at which three equal borders and thus three equally administered territories ( states , member states , administrative units, etc.) meet. Such tri-border areas are mostly known when they have existed for a long time or when three cultures meet. Usually this point is marked by the respective national flag or monument . While three countries often meet, four- or multi-country corners are very rare.
General overview
Of the currently (2015) 195 states on earth recognized by the United Nations , 135 have at least one such boundary point. There are a total of 159 three-country corners on earth. The frequency of occurrence of three-country corners depends on the number of neighbors , but also on the number of sea borders . So have island nations like Japan or also states like Portugal , Denmark and San Marino , which only have one neighboring country - z. B. because they are completely surrounded by a state - none. Two neighboring countries are also not a sufficient criterion, as z. B. with respect to the USA in North America . The area of a country also has only a limited relationship to its number of triangles: The country with the most is the People's Republic of China with 16, while Russia , the largest country in the world in terms of area, has only 10.
Austria has nine three-country corners at its borders (making it the country with the most three-country corners in Europe), Germany seven, Switzerland six, and Liechtenstein has two three-country corners.

Europe
There are 48 international three-country corners in Europe:

Albania | Greece | North Macedonia | in the Prespa lake |

Albania | Kosovo | Montenegro | Tromeđa (2366 m) north of Bajram Curri in Albania |
Andorra | France | Spain | in the Pyrenees (Osteck) |
Andorra | France | Spain | in the Pyrenees (Westeck) |
Belgium | Germany | Luxembourg | in the Our River and near the European Monument , west of Sevenig (Germany), south of Ouren (Belgium) and east of Lieler (Luxembourg) as well as immediately south of a footbridge over the Our. In fact, this is not an exact point, but a line. Background: The border between Belgium in the north and Luxembourg in the south is formed by the valley path around the Ribbach, which flows east to the Our . The border between Belgium in the west and Germany in the east is north of the confluence of the Ribbach on the valley path of the Our flowing north. South of the confluence of the Ribbach into the Our, this river also forms the border between Luxembourg in the west and Germany in the east. However, the river itself is the common territory of these two countries ( condominium ), see Common German-Luxembourg Territory . For this reason, it is not possible to give an exact point where all three countries come together, but rather a line across the Our at the level of the valley path of the flowing Ribbach describes the situation. The corresponding area can be easily reached on foot from the car park at the European monument. |
Belgium | Germany | Netherlands | Vaalserberg west of Aachen (Germany), south of Vaals (Netherlands) and northeast of Gemmenich (Belgium) immediately east on a road between the last two places. This point was temporarily a quadrangle because of the neutral Moresnet . The area is well developed for tourism and a few meters to the north is the highest point in the European part of the Netherlands. |
Belgium | France | Luxembourg | in Chiers , east of Mont-Saint-Martin (France), in the west of the Rodange district of Pétange (Luxembourg) and south of Aubange (Belgium). The area around the border triangle is easily accessible from Luxembourg via a junction of the N5f, but not the exact point of the border triangle as this is located in a steep and densely overgrown depression of the stream. |

Bulgaria | Romania | Serbia | east of Negotin in Serbia |
Germany | France | Luxembourg | in the Moselle west of Perl (Germany), northwest of Apach (France) and east of Schengen (Luxembourg) as well as south of a bridge over the Moselle and west of the northern area of an island in the Moselle (also north of the weir in the Moselle). Similar situation to Germany, Luxembourg and Belgium. In fact, this is not an exact point, but a line. Background: The course of the border in the south of this area does not correspond to the course that one would expect from a map of Europe. On the one hand, the south-running border between Luxembourg (here) in the west and France (here) in the east begins here, this border being in the valley path of the Moselle. The border between Germany and France also begins at this one point in the valley path of the Moselle and runs first in an easterly direction and then in a southerly direction, also by land. France thus protrudes somewhat into this area in a northerly direction. In the north, the Moselle forms the border between Luxembourg in the west and Germany in the east. However, the river itself is the common territory ( condominium ) of these two countries, see Common German-Luxembourg Territory . For this reason, no exact point can be given for the meeting of all three countries, but a line across the Moselle at the level of the point mentioned in the valley path (at the level of the branching off of a riverside path from Rue Robert Goebbels ) best describes the situation . |
Germany | France | Switzerland | in the Rhine north of Basel (Switzerland), east of Hüningen (France) and west of Weil am Rhein (Germany) as well as south of the three-country bridge between France and Germany and north of a stele at the "Dreiländereck" named tip in the Rhine port of Basel. |

Germany, Austria, Switzerland
The following lists show lists of the triangle formed by the German and Austrian federal states as well as by the Swiss cantons. (The federal states and cantons are arranged alphabetically in ascending order.)
Germany
The 16 German federal states together form 15 triangle. Lower Saxony has the most triangle with 8, followed by Hesse with 6. Since Hamburg breaks the common border between Lower Saxony and Schleswig-Holstein, these three states form two triangle. Berlin , Bremen and the Saarland do not form an inner-German border triangle, as they only border on a different federal state.
Austria
The nine Austrian federal states together form five triangle. Most of the three-country corners are in Styria with four and Salzburg with three. Vorarlberg and Vienna do not have a (inner-Austrian) border triangle.

Switzerland
The 26 Swiss cantons together form 45 triangle. The canton of Bern has the most triangle with 14. The cantons of Basel-Stadt , Geneva and Schaffhausen do not have a triangle.
Former border triangle
As a result of border shifts, it happens that the previous triangle become part of normal state borders or are entirely within the territory of only one state (e.g. the former triangle in present-day Poland ), but still remain a prominent point. As a result of the countless global border shifts over time, only a few significant former three-country corners can be listed here.
