Museum on Main is a great place to explore the history of the Tri-Valley region.  We tell the fascinating stories of those who came before - illustrating characters, places and events that have shaped our region. These tales capture the hears of people in our region today, enabling them to connect with our rich heritage.  Museum on Main is the steward of our community's historical treasures. Through our exhibits, archives, artifact collection, photographs  and kid's corner we speak to the character of the Tri-Valley.
