Location and current use
Camp Callan was located near

History
Acquisition
On October 9, 1940, the San Diego City Council leased the
U. S. military of land for a nominal one dollar per year. The city council also leased an additional to the military. Margaret C. Hawkins leased the military and F.T. Scripps, Inc. leased them . The military acquired by revocable permit from the city council and by license from the city council. Altogether, of land for the base was authorized for acquisition by the government.
Early period of operation
On November 22, 1940, the
War Department announced plans to create a replacement training center for
coast artillery units in the Torrey Pines Mesa area. Men inducted into the military under the
Selective Service Program would be assigned to this new training center. The purpose of this training center was to teach trainees how to fire long-range weapons in the event the

. This training center was named "Camp Callan" in honor of
Major General Robert Emmet Callan, a distinguished Coast Artillery officer.
Construction of the base began in November 1940 and official occupation of the camp was marked by a military flag-raising ceremony that took place on January 15, 1941. Twenty officers and one hundred and twenty enlisted men were present. They were all members of the first unit of operations personnel at the new base. Brigadier General Francis P. Hardaway was the new camp's first commander. He spoke on the importance of the camp to the defense program at this ceremony.
On February 24, 1941, the first large guns arrived at the camp. Nine of these guns were French-made 155 mm guns that dated back to

had
inflicted on the United Kingdom so they decided to place full training emphasis on anti-aircraft weapons rather than on a combination of seacoast artillery and anti-aircraft weapons. This change marked the beginning of a two-year period of peak activity for the camp. Approximately fifteen thousand trainees were going through their training during each thirteen-week training cycle.
Training ranges on the base included a 1,000-inch range, a 200-yard rifle range, a pistol range, an automatic weapons range and a 3-inch anti-aircraft gun range. The trainees learned to use 155 mm, 90 mm, 75 mm, and 40 mm caliber guns as well as the associated
fire control equipment. Gun firing positions were established for this training.
In addition to artillery gun positions and small arms ranges, a variety of other facilities and structures were built on the base. These improvements included barracks and cantonments, a 910-bed station hospital, offices, five
Post Exchanges, three theaters, five chapels, support buildings, storage buildings and a landfill. In all, the developed part of the base covered twenty-three blocks and had over 297 buildings at this time.
Various living amenities were provided for the health, general education and war training schooling of the trainees, much like other Army camps of the time. A weekly newspaper called ''The Range Finder'' and an annual pictorial review called ''The Callander'' were published at the camp. The camp eventually got its own 40-piece military band as well.
Late period of operation

In the last group of recruits attending Coast Artillery basic training at Camp Callan, was
Donald Prell, who in June 1944, graduated from OCS at Ft. Benning, GA. In June 1944, the training emphasis at the camp was again to change. The anti-aircraft training program was transferred to

, and the camp assumed an important role in preparations for massive overseas
amphibious assaults. However, this period of camp activity was short-lived. By May 8, 1945,
the war was over in Europe and by August 15
the Japanese had surrendered. Because of these changes, this training was no longer needed. On November 1, 1945, Camp Callan was declared surplus.
Disposal
After the camp was declared surplus, the land it was on was disposed of over the course of a year. and an additional of leased land was cancelled on March 25, 1946. of leased land was cancelled on August 9, 1946. of leased land was cancelled on June 30, 1946. of permit land was cancelled on December 13, 1945. {{convert, 12.85, acre, m2 of licensed land was cancelled on March 25, 1946.

was facing a shortage of lumber and building materials. This problem was made worse because many veterans chose to stay in San Diego after the war. In order to mitigate this problem, the San Diego City Council negotiated with the War Department to acquire most of the buildings and facilities of the camp (which numbered around five hundred at the time the camp closed). The selling price was $200,000. These material were then resold to veterans and other citizens at reasonable prices. Several thousand homes, several churches and many utilities were constructed from this material. The city recouped its $200,000 investment and made a $250,000 profit on these sales. Part of this profit went to build the Veteran's War Memorial Building in
Balboa Park.
Today, almost all evidence of improvements or buildings built on the former base during its existence (except the landfill) have disappeared. A few foundations remain in the area to the north of the UC San Diego campus. The old main entrance of the base is at The Lodge Torrey Pines off of Torrey Pines Road.
