The inner part of the coin shows a representation of the Cathedral of Cologne with a comet in the upper part of the design. The words ‘XX GIORNATA MONDIALE DELLA GIOVENTU'’ form a quasi-semicircle along the upper edge of the inner part, interrupted by the tail of the comet and one of the church spires. Twelve stars in a quasi-semicircle appear on the upper part of the outer ring. At the top, within the outer ring, the year of mintage (2005) and the mintmark ‘R’ are inserted between the stars. On the lower part of the outer ring the words ‘CITTA' DEL VATICANO’ form a semicircle.
