The Petaluma Historical Library and Museum, located at 20 4th Street, is a former Carnegie Library that now houses regional history exhibits, cultural and community events, and a gift shop.
The building is built in the neo-classic style, featuring original fan-glass windows, round leaded-glass windows, and original interior wood paneling and columns. It also features the largest free-standing leaded glass dome in Northern California.
The Museum's Research Library contains books and files that assist in history, genealogy, and architectural research of Petaluma and the surrounding area. It is staffed by dedicated volunteers and open to the public on Thursday afternoons from 1:00pm-4:00pm.
