The main house, Temelec Hall, was built in 1858-1859 for Captain Granville P. Swift.","why_significant":"The nomination argues the property is significant for its association with Captain Granville Swift, a California pioneer who took part in the Bear Flag Rebellion and served in the California Battalion. It also presents Temelec Hall as a rare stone Greek Revival house in California that retains its integrity, along with its original service buildings and grounds.","narrative":"Temelec is a group of stone buildings and gardens just south of Sonoma, centered on Temelec Hall, a two-story Greek Revival mansion completed in 1858-1859 for California pioneer Captain Granville Perry Swift. The walls are dressed gray ashlar with white stone trim, with porticos and balconies on three sides. Nearby stand a smokehouse and kitchen, a carriage house and barn, a washhouse, two stone gazebos, a swan fountain, long stone walls and a former fishpond now used as a reservoir. No architect is recorded. Later owners, including the Coblentz family, altered the site with respect for its layout, and it was named California Historic Landmark #237 in 1936. A retirement community now surrounds it, and the hall serves as its clubhouse. The nomination highlights Swift's role in the Bear Flag Rebellion and the California Battalion, and the rarity of a stone Greek Revival house in the state.","period_of_significance":null,"architect_builder":"Built by Captain Granville P.
