Captain William G. Dana, a New England sea captain and grantee of the land, began building the 13-room house in the fall of 1839. It was among the largest buildings in the area, second in size only to Mission San Luis Obispo de Tolosa. The adobe served as a stopping place for travellers and as a working ranch centre. Rooms at the rear housed a carpenter and blacksmith shop and a weavery and store, and candles and soap were made on site. Goods went to neighbouring ranchos and to the missions of La Purisima and Santa Ynez. Visitors included John C. Fremont, Edwin Bryant and Capt. Halleck, and mail riders exchanged pouches here.
