Can somebody explain where the three different Luxembourgs are located?

Question

I was putting destination in kayak and came to know that there are three different Luxembourgs. According to kayak it is as below -

1. Luxembourg - This is apparently the country with orage-white-blue shaded flag.
2. Another Luxembourg is Luxembourg, Belgium
3. The last one is Luxembourg, Mosel, Europe.

I am guessing these are 3 different places. I am looking for the one which is supposed to be near Schengen area, where the European agreement was signed. Does anybody have a clue which one is it?

Answer 1

There are a few things called Luxembourg and that might create some confusion:

1. A small country located at the corner between Belgium, France, and Germany. The color of the flag is more red than orange. It was ruled by the House of Orange between 1815 and 1890 and the shape of the flag inspired by that of the Netherlands but I don't think it ever included the color orange, unlike the Dutch flag.
2. The capital of this country, sometimes called “Luxembourg City” or “Luxembourg-Ville” (also the name of the main train station I think).
3. The Belgian Province de Luxembourg, a region of Belgium located just next to the country named in point 1.

Now, Schengen is a village on the Luxembourgish side of the border tri-point between Luxembourg, France, and Germany. The agreement itself was signed on a riverboat, so as to symbolically be “on the border” without knowing exactly in which country (although for legal purpose, it's considered to be Schengen and Luxembourg is the depositary of the original treaty). The boat, called “Princesse Marie-Astrid”, still does cruises on the Moselle river.

Finally, Schengen is very small, I don't think the area around it was ever known as “Schengen area” in any of the local languages. What's now called “Schengen area” is typically the whole 20+ country strong border-free area.

Answer 2

"Luxembourg" refers to various parts of a former medieval Duchy of that name.

The namesake part of the Duchy is a country of that name. To the west is a former part of the country that was occupied by Belgium in 1839, and is the (Belgian) province of Luxembourg.

"Luxembourg" could refer to one (of three) districts in the country that goes by that name.

Finally, it could refer to the capital city (located in the district mentioned above).
