During Santa Rosa’s 150-year history there have been several catastrophic events that have wiped historic landmarks from the map forever. Major natural disasters like the 1906 earthquake or the 2017 wildfires, obliterated whole neighborhoods from the landscape in an instant.

With the exhibition “Lost Santa Rosa,” the History Museum of Sonoma County explores moments of transformative change, from major natural disasters to more subtle transitions.

We have all mourned the destruction of the old Fountaingrove Round Barn, but did you know that Santa Rosa also had a Chinatown?

The exhibit runs from April 14 to Sept. 16 and contains photographs and ephemera associated with landmarks from Santa Rosa’s past.

A kickoff reception will be held May 6 at the Seventh Street museum from 3 to 5 pm. Admission is $7-$10, or free for children under 12 and museum members.
