Since the first edition in 1952 held in Barcelona, the Congress has been the main and most important global event for associations, federations, friends and enthusiasts of the crèche who come together in a great moment of true universal crib fraternity.
Since 1988, it has been organised regularly every four years in a state, region and/or different location, where hundreds and hundreds of nativity scene designers from all over the world have the opportunity to meet and discover all crib traditions in the area, which is chosen and approved after a careful analysis by the Un.Foe.Prae. International Council.
