Oblique aerial view
of the Merced Assembly Center.
The Merced Assembly Center, in the central San Joaquin Valley,
was within the town of Merced at the county fairgrounds. Occupied
from May 6 to September 15, it housed a total of 4,669 people
(with a maximum of 4,508 at one time) from the northern California
coast, west Sacramento Valley, and the northern San Joaquin Valley.
Historical photographs show about 200 buildings at the assembly
center, most located south of the fairgrounds proper (see above).
A State of California historical marker
is located at the main pedestrian entrance to the fairgrounds.
Some fair buildings visible on the 1942 aerial photograph may
remain, but there have been extensive changes at the site. Behind
(south of) the fairgrounds the former barracks area is now a gravel
parking lot. Eleven concrete foundations there may be from the
assembly center: the slabs are in poor condition, but most measure
approximately 20 ft by 100 ft, the standard barracks size Concrete
floors for temporary barracks were unusual, if not unique, given
the assembly centers' hasty construction. The only relocation
center with concrete barracks floors was Granada, where, coincidentally,
the internees at Merced were transferred.
With the departure of the Japanese, the
installation was turned over to the 4th Air Service Area Command,
although the 1945 inventory of Army facilities still listed it
as a Japanese Assembly Center. Later in 1942, Army personnel
arrived at the fairgrounds for training, including a chemical
warfare section and an infantry unit. It is possible that this
post was named "Camp Merced." During the war years,
about 5,500 black troops also were quartered there. After the
war, the fairgrounds was turned over to the 35th District Agricultural
Association and thefair returned in 1946 with a record-breaking
attendance of 30,000.
