Von Pfister Adobe History


This adobe was the third building erected in Benicia, constructed by Wm MacDonald for Robert Semple in 1847. Before it was completed it was rented to Captain E.H. Von Pfister for use as a store.

This adobe is representative of an important link in the transitional phase of culture and architecture as Spanish California gave way to America?s California. With limited building materials and without the machinery to produce building utensils, the early Californian adopted a form of building type with which they were not wholly familiar. The result was a hybrid form of construction combining southwest and east coast American architecture.

Spanish and Native American adobes were normally built with no foundation, or else on a base of natural stone rubble which was then plastered over. The Von Pfister adobe has a foundation of quarried cut stone laid as a foundation beneath its adobe mud walls, as though for a wood frame or masonry building. Similar buildings exist at the American government built Fort Union in New Mexico. The adobe walls are constructed with mud mixed with straw as a binder, shaped into bricks and sun-dried. In 1847 Von Pfister added a wood frame one story addition to the unfinished adobe, and constructed an enclosed loft space above the adobe. At some point the

The Von Pfister adobe's construction lasted well over 100 years. The wood sheathing that protected the adobe from rain also sheltered it from observation and the constant replastering required to keep adobe intact and pest free. In 1986 the State of California designated the crumbling adobe an archaeological site and in 1992 a shelter was installed to help protect the structure from the strong Carquinez strait winds.
