Facade of the San Mateo County History Museum

The History Museum is located inside the 1910 County Courthouse. On the National Register of Historic Places, the courthouse features a stained glass dome and mosaic tile floor. Architect Glenn Allen designed the building to look as impressive as City Hall in San Francisco.


Exhibits depict the history of the Peninsula from the original Native American inhabitants to today. They help place local history in context by showing how the story here has influenced the outside world, and how the outside world has influenced it.

History of the Courthouse

Early History

San Mateo County has built four courthouses on the block of land originally donated by Simon Mezes and the Arguello Family, owners of Rancho Las Pulgas. The top floor of the 1858 courthouse was destroyed in the 1868 earthquake. The remaining floor was used until a new courthouse was built in 1882. It was known as the “Lady Justice” Courthouse for the statue of Lady Justice on top.

The 1906 Earthquake

Due to the growth of the county and the desire for a grander building, a third, larger courthouse was designed just behind the second one. Completed shortly before the 1906 earthquake, only the dome structure survived.

County Government

In the early 1900s, the courthouse was home to all county government. In addition to the courtroom, the Board of Supervisors, Sheriff, Coroner, Auditor, Treasurer, County Clerk, Assessor, Tax Collector, District Attorney, Recorder and Superintendent of Schools had offices in the building. It also housed work areas for the County Engineers.

The Courthouse is hidden by the Fiscal Building.

In 1939, the front facade of the building was removed and the Fiscal Building was added. In 1941, a second annex was added to the back of the building. Both buildings were WPA projects. In 1958, an 8-story building called the Hall of Records and Justice was built near the courthouse.

Becoming a Museum

By the 1990s, the courthouse no longer met modern court needs. In 1998, the San Mateo County History Museum had the opportunity to move into the building. The History Museum has developed exhibits where you can explore the county’s rich and colorful history
