On the Grid : Centinela Adobe
"The Centinela Adobe, also known as "La Casa de la Centinela", is a Spanish Colonial style adobe house built in 1834 by Ignacio Machado. It is operated as a house museum by the Historical Society of Centinela Valley, and it is one of the 43 surviving adobes within Los Angeles County. The Adobe was the seat of the 25,000 acre Rancho Aguaje de la Centinela, which was a Mexican Alta California-era piece of land granted by Spain to Mexico." - Aero Collective
