Artesonado

Artesonado or Spanish ceiling is a term for "a type of intricately joined wooden ceiling in which supplementary laths are interlaced into the rafters supporting the roof to form decorative geometric patterns",[1] found in Spanish architecture.

Artesonado decoration is usually in regular recesses between the rafter beams and the woodwork is gilded or painted.

It originated in the Islamic regions of North Africa [citation needed] and Al-Andalus, as can be seen at the Nasrid palace of the Alhambra, and was introduced into the Iberian Christian kingdoms by Muslim craftsmen [citation needed] during the Christian reconquest of the Iberian Peninsula.

[1] Notable examples of artesonado ceilings include those in the throne room of the Aljafería (Zaragoza), the Chapterhouse of Toledo Cathedral, and the Royal Convent of Santa Clara (Tordesillas).

[2] Original artesonado ceilings, although expensive to transport and difficult to reassemble, were bought by private collectors during the 20th century and can be currently found, for example, in the Hearst Castle, Metropolitan Museum of New York, Fine Arts Museum of San Francisco, Tomas Aquinas College of Ventura County, Worcester Art Museum and Instituto Helenístico de Ciudad de México.
