A sign at Cabrillo National Monument reads:
"On March 31, 1933, President Franklin D. Roosevelt signed into law an act creating the Emergency Conservation Work Program, better known as the Civilian Conservation Corps (CCC). This program became one of the most popular and successful of Roosevelt's "New Deal" programs designed to bring pre-war America out of the Great Depression.
Between 1933 and 1942, when the CCC program ended, a total of 2 million enrollees had worked in 192 camps in 94 National Park Service areas as well as 697 camps in 881 state, county and municipal areas.
The American people continue to benefit from the many CCC trails , structures, conservation projects, and other improvements carried out in National Park Service areas such as Cabrillo National Monument. The CCC enrollees themselves continue to benefit from the satisfaction of a job well done at a critical juncture of American History."
Although the CCC no doubt worked on several projects at Cabrillo...this website (
visit link) verifies on p. 24 that the Visitors Center was built by the CCC:
"Mission 66 Visitor Center
After World War II, prosperity and optimism
encouraged thousands of Americans to visit
their national parks. The need for a systematic
method of communicating to park visitors led
to the decade-long project (1956–1966) known
as Mission 66. Before Mission 66, most park
and monument structures were rustic-style
buildings constructed by the Civilian
Conservation Corps (CCC). Mission 66 designers
took a different path, using contemporary
and commercial designs for the new buildings.
Visitor centers, prominently situated at entry
roads, welcomed the masses with orientation
information and other amenities, and they soon
became emblems of a new era for the National
Park Service. Cabrillo National Monument’s
visitor center is a product of the Mission 66
movement and reflects this time period."
