Gigantes y cabezudos

Many Spanish festivals include costumed figures known as gigantes y cabezudos, roughly, “Giants and Big-Heads”, in Valencian, "Gegants i cabuts", in Catalan, gegants i capgrossos, or in Basque, "erraldoi eta buruhandiak". The main feature of these figures is typically their papier maché head; bodies are covered in clothing matching the costume's theme.

The giants are usually hollow figures several meters tall, with a painted paper maché head and arms, the rest of the body being covered in cloth and other clothing. Their frame is usually made of wood or aluminum, with carton-pierre—a mixture of papier-mâché and plaster of paris— used to make the head and hands. The frame of the body is hidden by cloth, and arms typically have no structural element to allow them to swing in the air when the giant is turned.

Within the frame is an individual controlling the giant. He carries a harness on his shoulder that is linked to the internal structure, and will move and shake the giant in a dance, usually accompanied by a local marching band. Typically, these dances will include at least two giants, the male gigante and the female giantess, called giganta or gigantona, though some towns have multiple couples.

The figures usually depict archetypes of the town, such as the bourgeois and the peasant woman, or historical figures of local relevance, such as a founding king and queen, or pairs of Moorish and Christian nobles.

Cabezudos are smaller figures, usually to the human scale, that feature an oversized, carton-pierre head. The heads are worn with a matching costume. The person dressed as cabezudo will use one hand to hold his head, while the other hand carries a whip or pig bladder, used to frighten children or young women. Seeing through the “mouth” of the head, he will chase after these people, though he might pause to calm a frightened child.
