Tule Lake National Monument

The largest and most heavily militarized WWII Japanese American segregation center, preserved alongside Camp Tulelake in Northern California.

Tule Lake National Monument, located in Modoc and Siskiyou counties in Northern California near Newell, preserves the largest and most controversial of the ten concentration camps built by the United States government during World War II. Established as a National Monument in 2019 after previously being designated part of the World War II Valor in the Pacific National Monument in 2008, the site encompasses two distinct historic areas: the Tule Lake Segregation Center and Camp Tulelake. Between 1942 and 1946, more than 29,000 people of Japanese ancestry were incarcerated at Tule Lake, two-thirds of whom were United States citizens. In 1943, the facility was converted into a high-security segregation center to isolate those prisoners who protested their confinement, resisted the draft, or refused to answer or answered negatively to the government's controversial loyalty questionnaire.

The physical remnants of the Segregation Center stand against the backdrop of Castle Rock, a massive geological formation also known as the Peninsula. The most prominent surviving structure is the historic concrete jail, which was built under the supervision of incarcerated carpenter Jimi Yamaichi, who later co-founded the Japanese American Museum of San Jose. This stark, multi-cell building served as a maximum-security lockup within the already heavily militarized camp, which featured double barbed-wire fences, nineteen guard towers, and a garrison of soldiers. Visitors can explore the jail on ranger-guided tours, which are offered seasonally from Memorial Day through Labor Day. Beyond the segregation center, Camp Tulelake, located a few miles away on Hill Road, originally served as a 1930s Civilian Conservation Corps camp before being repurposed to house Japanese American strikers and, later, German prisoners of war.

A new visitor center opened in June 2022 along Highway 139, replacing a cramped ten-by-ten-foot rented office at the local fairgrounds. This modern facility features comprehensive historical exhibits, a bookstore, and an outdoor display representing the ten War Relocation Authority camps, fabricated in part by local youth. The visitor center serves as the starting point for interpretive programs that detail the complex legal and social struggles of the inmates, including the mass renunciation of citizenship under duress and the subsequent legal battles led by civil rights attorney Wayne Collins to restore their rights. While the main historic jail is accessible during the summer tour season, the surrounding grounds remain a place of quiet reflection, where the foundations of barracks and administrative buildings evoke the scale of a confinement site that once held a peak population of 18,700 people.
