Your donation helps protect and preserve Costa Mesa history.

The Costa Mesa Historical Society is a 501(c)(3) nonprofit, 100% volunteer organization. It is not a city department. Rather, it is kept alive by people like you who are dedicated to preserving and promoting the history of Costa Mesa.

Each year, the society promotes our history through regular public events, community collaborations, and its vast collection at two museums. The society’s collection contains some 1,500 books, 30,000 photos, and 100 GB of newspapers, as well as countless personal archives, maps, oral histories, digital media, textiles, and more — all available to view by the general public.

We can only accomplish these goals through your support.
