Camp Ono, Former military installation in San Bernardino, California, United States.
Camp Ono was a military installation near San Bernardino that spread across extensive grounds with housing quarters and maintenance stations. The facility supported military operations and connected to regional railroad networks.
The installation was founded in 1942 and held around 500 Italian prisoners of war during World War II while supporting military logistics. It closed in 1947 as the war ended.
Italian military units used the site during the war for vehicle and equipment maintenance work. Their labor formed part of the larger war effort coordinated across several depot companies.
The site is not publicly accessible today and sits within a designated environmental protection area that covers the former military grounds. Visitors should check ahead about which areas may be reached and what restrictions apply.
After the war, the grounds were converted into a truck cleaning facility, abandoning its original military purpose. This reuse eventually led to soil contamination and designation as a Superfund cleanup site.
