Christmas Tradition in Spain

In Catalonia, as well as in the rest of Spain and in most of Italy and Southern France, traditional Christmas decorations often consist of a large model of the city of Bethlehem, similar to the Nativity scenes of the English-speaking world but encompassing the entire city rather than just the typical manger scene. This pessebre is often a reproduction of a pastoral scene—a traditional Catalan masia (farmhouse) as the central setting with the child in a manger, and outlying scenes including a washerwoman by a river, a woman spinning, shepherds herding their sheep or walking towards the manger with gifts, the three wise men approaching on horseback, an annunciation scene with the angel and shepherds, the star pointing the way, etc. Commonly materials such as moss will be used to represent grass, with cork used to represent mountains or cliffs.

The caganer is a particular and highly popular feature of modern Catalan nativity scenes. It is believed to have entered the nativity scene by the late 17th or early 18th century, during the Baroque period. Eminent folklorist Joan Amades called it an essential piece and the most popular figure of the nativity scene. [...] There is a sculpture of a person defecating hidden inside the cathedral of Ciudad Rodrigo, Province of Salamanca, though this is not part of a nativity scene. Accompanying Mary, Joseph, Jesus, the shepherds and company, the caganer is often tucked away in a corner of the model, typically nowhere near the manger scene. A tradition in the Catalan Countries is to have children find the hidden figure.
