: D wie Düsseldorf

:D The challenge!

Listing Stand 14.07.2022

Düsseldorf will be 725 years old this year. For this special city anniversary, some caches were placed in the city of Düsseldorf. You can recognize this by the presented :D. As you can see, this cache is also part of the series. If you also want to congratulate the city on its birthday, then take part in this challenge:

Put together the lettering 725 Jahre Düsseldorf from parts of the caches you have found so far.

You can use individual letters and numbers from the titles of your finds as well as syllables, words or whole numbers.

An example from my finds:
A72 - RS Vogtland Nord von auge 2865 | GC1NDB4 | Sachsen, Germany
Der "08/15" Cache von Hotbina | GC43VM8 | Nordrhein-Westfalen, Germany
Eisbergen 1111 Jahre - Der weite Blick - von daxton | GC14HKM | NRW, Germany
Düsseldorf - Nippon (für Ulrich...) von zutuu | GC2F89B | NRW, Germany

Can you do this challenge with fewer caches? Or - and that would make us particularly happy - can you install other caches from the :D series? We look forward to your creative compilations.

Please name the caches you found in the internet log and mark the relevant passages or attach a photo as proof.

Now to the cache:
To find the cache, determine the exact
Date of birth of the city of Dusseldorf.
Add the day + month + year to the number X and put it in the following formula:
N51° 13. [X - 583] E006° 46. [X - 559]


Every geocache of the :D series contains a bonus code. Please write it down, you will need it in order to log the two bonus caches GC49RXJ and GC44Q3J!

Additionally you can track every bonus code at


There is no geocache to find at the listed coordinates. No cache which is part of the :D series requires to trespass rail tracks or highways. Caches located on private property have been placed there with explicit permit of the owner. If a riddle requires visiting third party websites or downloading additional files, we guarantee that at the time of publish, they don't contain any virus or harmful software.
