Uses of Gypsum in Spanish architectural heritage: Typologies and some unique construction techniques.

In Spain, gypsum and its many typologies play an important role as a construction material in Spanish architectural heritage. Its historical use is mainly a direct consequence of the abundance of gypsum deposits and a constructive tradition which began in ancient times. In addition to being a sign of constructive identity, gypsum is a clear example of the strong link between traditional architecture and the natural resources of the territory. The aim of this article is after to identify gypsum deposits and gypsum architectural heritage found in different parts of Spain and to explain the different gypsum typologies—other than powdered gypsum—used. Finally, the most unique construction techniques are described, differentiating between structural elements, partitions, and enclosures, as well as architectural elements and surface finishes.
