The original downtown is still the town's main commercial area, and many buildings keep their original scale and uses. The architecture ranges from Greek Revival and Queen Anne to Mission Revival and California bungalow.","narrative":"Magnolia Avenue in Larkspur, Marin County, forms the core of the town's Old Downtown, a district of 52 structures stretching from the Lark Creek Inn to the Lark Theatre and the railroad station. The area grew after land developer C. W. Wright bought the King family dairy ranch in 1875, auctioned lots, and persuaded the railroad to build a station. The 1929 Mission Revival station still stands at the district's eastern edge. Magnolia Avenue, once called the County Road, became a main north-south route through Marin County, and the Blue Rock Hotel drew visitors from San Francisco from the 1890s through Prohibition. Today the original commercial area remains the main commercial area, with the hotel, bank, theatre, barber shop and grocery still in business use. Styles range from Italianate and Queen Anne to Mission Revival and bungalow. About 72 percent of the buildings, mostly commercial structures built between 1880 and 1930, survive, and the original scale of most remains intact.","period_of_significance":"1890's-1930's","architect_builder":null,"architectural_style":"Mixed styles: Greek Revival, Italianate, Queen Anne, Mission Revival, California bungalow","criteria":[],"status_note":"Still the main commercial area of Larkspur; the hotel, saloon, barber shop, grocery, bank and theatre still have commercial uses, and City Hall and some residences keep their original purposes.
