Below there are 16 cities all across Europe (and surroundings). One of them connects them all.

Besançon  |  Ankara    |  Wrocław    |  Katowice
Orléans   |  Plovdiv   |  Munich     |  Debrecen
Nice      |  Chișinău  |  Hannover   |  Linz
Béziers   |  Bursa     |  Stuttgart  |  Lviv

You'll have to do the same 5 times. If you find the city, you will be able to check if it's indeed the one we are looking for.

    $\begingroup$ @msh210 This could be a clue. Things like the Eurovision song contest or different european sports competitions use different definitions of what constitutes Europe. Maybe this puzzle isn't purely geography based. $\endgroup$

    $\begingroup$ @quarague, nope, it isn't a clue. I just didn't thought about it. $\endgroup$

    $\begingroup$ A map that some might find useful (coloured by column)... And one with some 'connections' that didn't lead me to a clear answer... Might spark something in somebody else. $\endgroup$

1 Answer 1


The meaning of "connect" in this question is:

If you have four cities, "connecting" them means finding two pairs of cities, whose geodesics intersect, and finding the intersection point. To put it another way, we use the cities to make an X shape, and then find the center of the X.

If we use this 'connection' process for each one of the columns, we get:

1. Lyon

2. Istanbul

3. Nuremberg

4. Zakopane

So now, we get four cities. The obvious next step is to use the connection process again. If we do this , we have


"You'll have to do the same 5 times"

We use this connection process 5 times.

"If you find the city, you will be able to check if it's indeed the one we are looking for"

If we take the initials of every one of the cities obtained from our first four connection processes, we get LINZ.

Great thanks to @Stiv for helping me with the idea of connections, and the OP for suggesting round lines.

  • $\begingroup$ @Lezzup Got it! Also, may you please help me with the imgur link? Somehow it doesn't show up, even if I use the standard convention $\endgroup$ Jul 10, 2023 at 22:31
  • $\begingroup$ If the missing one is this place then the initials of the places you found sure look handy... (Consider reordering them to match the column order...) You should probably also explain what you mean by 'connect' in your opening line, for ease of understanding :) $\endgroup$

    $\begingroup$ By the way, it was quite a tough one to find 4 cities for which this would work.. and not ending up with some little villages. $\endgroup$
