What they are: Adobe buildings are constructed using adobe bricks, made by mixing clay-rich mud, straw, animal manure and sand in a pit. The mixture is then shoveled into molds and left to bake in the sun.
When they arose: Adobe construction was introduced to California by the Spanish in 1769. The Spanish used adobe widely, and every Spanish presidio, pueblo and mission was made up almost exclusively of adobe buildings.
Details: These buildings were also used later on during the Mexican and early American periods of California.
