A mudbrick is a firefree brick made of clay, or mud mixed with a binding material such as rice husks or straw.
In warm regions with very little timber available to fuel a kiln, bricks were generally sun dried. This had the result that their useful lifespan is reduced to around thirty years. Once a building collapsed, new bricks would have to be made and the new structure rebuilt on top of the rubble of the decayed old brick. This phenomenon is the primary factor behind the mounds or tells on which many ancient cities stand.
Adobe is a type of mudbrick also used today to save energy and is an environmentally safe way to insulate a house.
The Great Mosque of Djenné, in central Mali, is the world's largest mudbrick structure.

Ancient world
The South Asian inhabitants of Mehrgarh constructed, and lived in, mud brick houses between 7000–3300 BCE.1 Mudbricks were in use in the Near East during the aceramic Neolithic B period. The Sumerians used sun-dried bricks in their city construction;2 typically these bricks were flat on the bottom and curved on the top, called plano-convex mudbricks. Some bricks were formed in a square mould and rounded so that the middle was thicker than the ends.
In Minoan Crete at the Knossos site there is archaeological evidence that sun-dried bricks were used in the Neolithic period (e.g. prior to 3400 BC).3
Mudbricks were used to some extent in pre-Roman Egypt, and mudbrick use increased at the time of Roman influence.4
