It was built about 1878-1880 on the Dickerman ranch, part of the Steele Brothers dairy ranches.","why_significant":"The nomination calls it the last surviving dairy barn on State Landmark No. 906, the Steele Brothers Dairy Ranches. It is a rare example of peg (mortise and tenon) construction and an eastern-style tall barn, unlike most California barns. It also reflects the pioneer artisans and the coastal dairy industry, and its large redwood timbers were salvaged from the Waddell Wharf.","narrative":"Near Año Nuevo Point south of Pescadero, a large redwood barn sits on a hilltop with views toward the Pacific Ocean. Built about 1878-1880 for the Dickerman ranch, it measures 40 by 91 feet and rises roughly three stories under a gable roof, a form more common in the eastern United States than in California. Its 18-inch redwood uprights are joined with mortise and tenon connections and long wooden pegs. Many timbers were salvaged from the Waddell Wharf in nearby Año Nuevo Cove. The barn is the last dairy barn surviving from the Steele Brothers Dairy Ranches, a state landmark covering about 7,000 acres. It illustrates the pioneer craftsmanship and the coastal dairy industry, which depended on shipping by sea. After decades without maintenance, the state stabilized it by 1981 with a new roof, new south wall siding and rebuilt ramps. The remaining three walls were kept intact.","period_of_significance":"1878-1880 (specific dates; checked century 1800-1899)","architect_builder":null,"architectural_style":null,"criteria":["C"],"status_note":"Owned by the State of California Parks and Recreation.
