The Cesta is located on the highest of Monte Titano's summits. A museum to honor Saint Marinus, created in 1956, is located in this tower and showcases over 1,550 weapons dating from the Medieval Era to the modern day. It was constructed in the 13th century on the remains of an older Roman fort.

Designer: Arno Ludwig
Engraver: Luciana De Simoni

A geographical map of Western Europe spans the outer ring and inner core on the right side of the coin. The inscription 1 EURO is superimposed over the map of Europe, with the numeral “1” 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.”
