León Cathedral

Santa María de Regla de León Cathedral is a Catholic church, the episcopal see of the diocese of León in the city of León, Castile and León, north-western Spain, consecrated under the name of the Virgin Mary. It was the first monument declared by the Royal Order of Spain on August 28, 1844.

Initiated in the 13th century, it is one of the greatest works of the Gothic style, with French influences. Also known as the Pulchra Leonina, which means ‘Beautiful Leonese’, it is located on the Way of Saint James, or Camino de Santiago.The León Cathedral is mostly known for taking the “dematerialization” of gothic art to the extreme, that is, the reduction of the walls to their minimum expression to be replaced by stained glass, constituting one of the largest collections of medieval stained glass in the world.
