The Basilica di San Marino is a Catholic church located in the Republic of San Marino. While the country has a distinct domination of historic religious buildings of Christian faith, the basilica is the main church of the City of San Marino. It is situated on Piazza Domus Plebis in the northeastern edge of the city, adjacent to the Church of St. Peter. It is dedicated to Saint Marinus, the founder and patron of the Republic.

The present church was built in 1836 in place of an earlier one that dated to 7th century. It is built in the Neoclassical style, with a porch of eight Corinthian columns. Relics of St. Marino are enshrined in the basilica.

A geographical map of Western Europe spans the outer ring and inner core on the left side of the coin.

12 stars are located on the left 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 “0” in “10.”
