The Jack Mason Museum of West Marin History is located in the Inverness Public Library and is primarily an archive created to build upon local historian Jack Mason's extensive history collection. The Museum collects and preserves materials pertaining to the history of the Point Reyes Peninsula and Tomales Bay regions. Our mission is to enrich the community through exhibits, publications, outreach programs, and research opportunities. We seek to inspire public interest in West Marin history and to highlight its connection to contemporary life.
