National Register of Historic Places in Humboldt County
The Eureka Post Office and Courthouse is representative of the eclectic classicism which distinguished most public buildings designed by the Treasury Department's Supervising Architect's office in the early 20th century. Although it may not have succeeded in its role as exemplar of good taste to be imitated by subsequent private structures, the building is perhaps the most refined of the early public architecture of Eureka.
The tempera murals added to the courtroom in 1937 are Eureka's only federally sponsored decorative artwork executed during the Depression. The Eureka murals, which were more skillfully painted than most of their contemporaries, are excellent examples of the widespread social realist art movement of the thirties and forties.
