Depicts two contemporary pictorial elements. The Emperor's personal monogram and the octagon of Aachen Cathedral. Both motifs merge very skilfully into a central work of art of its own character. The work impresses with its dynamic, plastic design. The overall result is an innovative tribute to Charlemagne, an outstanding figure in European history.

The inner part also shows the lettering "KARL DER GROSSE" in the upper area and the year of issue "2023" in the lower area, the years "748 - 814", the country code "D" for the issuing country Germany, the mintmark of the respective mint ("A", "D", "F", "G" or "J") and the artist's initials ("TW"). The twelve stars of the European Union surround the design on the outer ring.

Aachen Cathedral (German: Aachener Dom) is a Roman Catholic church in Aachen, Germany and the seat of the Roman Catholic Diocese of Aachen. One of the oldest cathedrals in Europe, it was constructed by the order of Emperor Charlemagne, who was buried there in 814.

A geographical map of Western Europe spans the outer ring and inner core on the right side of the coin. The inscription 2 EURO is superimposed over the map of Europe, with the numeral “2” located in an open field representing the eastern Atlantic Ocean.

12 stars are located on the right side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “O” in “EURO.”
