Welcome
The mission of the museum is to preserve Southern Alameda County (Fremont, Newark and Union City) memories, documents, artifacts, and structures from the past and share them with present and future generations.
Our Exhibits
Visit the museum to learn about the history of the Tri-City, from the Mission and Rancho Eras through to pre-incorporation — back when Fremont, Newark and Union City were made up of farms, ranches and dairies, and later, after the cities incorporated, suburban communities. Visitors will discover how the waves of families who moved here lived, worked, and established a thriving small-town community.

Remembering Donna Olsen
It is with sadness and regret that we mourn the loss of Donna Olsen, an original organizer of the Tri-City Ecology Center in 1971, and a long-standing member and supporter of the Museum. Donna was instrumental in getting the Museum garden under control when it first opened. She planted all native plants around the Museum and ensured weekly upkeep would take place.
She was respected as a community activist, an environmental leader, an opinion shaper and a model for others to emulate. She was a true gem of Fremont, and a part of its long history, and she will be sorely missed. Read more about Donna’s many contributions to our community.
