Larkspur Downtown Historic District, Historic district along Magnolia Avenue in Larkspur, California.

Larkspur Downtown Historic District, also called Old Downtown Larkspur, runs along Magnolia Avenue from the Lark Creek Inn at 234 Magnolia Avenue to the platform of the former railway, now a bicycle path. Contributing properties include the Larkspur City Hall, the Lark Theater, the Blue Rock Hotel, a bank, the Silver Peso/Bob's Tavern, a barber shop, the railroad station and its buildings, and a concrete railroad platform.

The area developed as a commercial and residential center from the early 1900s through the 1930s when most of these buildings were constructed. In 1982, it was added to the National Register of Historic Places to preserve this architecturally diverse collection.

Magnolia Avenue has served as Larkspur's commercial hub since the town was founded. The Lark Theater and the Silver Peso/Bob's Tavern, both contributing properties, are among the landmarks that line the avenue. The district was recognized for retaining the feel of a small California town between 1900 and 1930.

The best way to explore the area is on foot, starting from Lark Creek Inn and following Magnolia Avenue to the converted railway platform. The street is easy to walk and gives visitors a clear view of the different buildings and their architectural details.

Many buildings that visitors see today started as homes but were converted to businesses over time. This transformation happened in ways that respected their original architecture, giving them a distinctive character that blends past and present.
