We are the Costa Mesa Historical Society: a non-profit, all volunteer organization dedicated to preserving and promoting the history of the city of Costa Mesa, the Santa Ana Army Air Base and the Harbor area.
We have two locations. Our downtown museum in Lion's Park, 1870 Anaheim Ave., is open Thursdays and Fridays 10a - 3p. Our Diego Sepulveda Adobe in Estancia Park, 1900 Adams Ave.(entrance on Boa Vista) is temporarily closed.
Come for a visit. Enjoy the displays. Share your stories.
Prints can be ordered from our extensive photo archives.
