Courthouse History - Thirteen zinc statues adorned the perimeter of the roof and the tower of this grand Italianate building in Eureka. Minerva, the Roman goddess of wisdom, was placed at the top of the tower, surrounded by four statues of Justice and others representing Flora, Ceres, Fortuna, and Juno. Minerva tilted in the 1906 earthquake, after which the statues were removed. The courthouse survived a fire in 1924, but another quake in 1954 cracked the building and the courthouse was vacated. In 1956, the condemned courthouse was demolished to make room for a more modern facility.
