The Etiwanda Historical Society

Located in the heart of historic Etiwanda!

CLOSED Due to CV19. Our 2nd Saturday Open Houses and ALL EVENTS are CANCELLED until further notice. Though we are closed, our groundskeeper and Board Members continue to work on Historic Preservation Projects. Please consider becoming a MEMBER and/or making a donation online via our online SHOP .

Our 2021 Project is installing our Australian Garden at Chaffey-Isle House. We are also hopeful to replace our wrap-around porch. Any and all donations are incredibly appreciated!
