The design features the Dome of St. Peter's Basilica, designed by Michelangelo, who worked on it until his death in 1564. Below, a section of the vault of the Sistine Chapel, apportioned and frescoed by Michelangelo. On the left, vertically, appear Michelangelo's autograph signature "michelagniolo", the letter "R" identifying the Rome Mint, and the name of the coin 's designer "D. LONGO" (Daniela Longo). The inscription "CITTA’ DEL VATICANO", indicating the issuing State, is arranged in an arc above the Dome. Just below, the years "1475", Michelangelo's birth year, and "2025", the year of issuance are inscribed. The coin’s outer ring bears the 12 stars of the European flag. (Source: ecb.europa.eu)
