The Cathedral of Leon is considered by certain art experts as the cathedral with the largest array of medieval stained glass windows the world over. Embarked upon during the second half of the 13th century, it was built to replace a Romanesque church that occupied the site of some 2nd century Roman baths.

Of Spain's Gothic cathedrals, that of Leon is the most heavily influenced by the French Gothic style. Reims Cathedral was the inspiration for its ground plan.

In deference to this symbolic structure, the Spanish Royal Mint will launch in collaboration with the Postal Service an issue of a sterling silver stamp and the associated artist's proof.

The proof depicts the main façade of the cathedral with its three grand portals and its towers, along with a view of one of its sides. The stamp portrays the White Virgin holding the Child, a replica of which can be seen on the main entrance mullion. The original sculpture, dating from the 12th century, is kept inside the cathedral.

Reproduced in sterling silver, the stamp is positioned at top left of the proof. It is accompanied by a certificate of authenticity issued by the FNMT-RCM, offset-printed on security paper.
