Come see the Contra Costa County Historical Society's current exhibit, Justice and Judges: The History of the Law in Contra Costa County. The exhibit is in honor of Judge Richard Arnason and features artifacts and court documents that belonged to him, as well as a brief history of the Judicial system as it has evolved in Contra Costa County.
The exhibit is open to the public during our open hours, Tuesday-Thursday from 9AM to 4PM, as well as the third Saturday of each month from 10AM to 2PM.
The Society recently received a substantial donation from the Contra Costa County Superior Court. The donation consists of artifacts and court documents that once belonged to Judge Richard Arnason, who passed away in 2015 at the age of 94. Judge Arnason served as a Superior Court Judge for 49 years, longer than any judge in the history of the county.
He was also the judge in the Angela Davis trial, in 1972, arguably one of the most significant (for both legal and political reasons) cases of the latter 20th century.
The donation was received from Judge Barry Goode, who suggested that an exhibit honoring Judge Arnason would be welcomed. The Society's Executive Director also saw the potential for using the materials to educate the citizens of Contra Costa County, and thus, an exhibit was born.

While cleaning up the map room recently, we came across a number of duplicate copies of our topographical county maps, along with a few that were from outside the county. We are making them available for sale, but please note that the quantities are quite limited and will be sold on a first-come, first-served basis. For information on what maps available, please click on this link.
CCCHS Past President and Curator of the San Ramon Valley Museum Beverly Lane has extended the great photos and research from our wildly successful exhibit on Electric Trains in Contra Costa County in 2012 into a booklet that the Society is proud to make available to the public.
