Naval Station Great Lakes
Naval Station Great Lakes is the home of the United States Navy's only boot camp, located near the city of North Chicago, Illinois, in Lake County. Important tenant commands include the Recruit Training Command, Training Support Center and Navy Recruiting District Chicago. Naval Station Great Lakes is the second largest military installation in Illinois and the largest training station in the Navy. The base has 1,153 buildings situated on 1,628 acres (6.59 km2) and has 50 miles (80 km) of roadway to provide access to the base's facilities. Within the naval service, it has several different nicknames, including "The Quarterdeck of the Navy," or the more derogatory "Great Mistakes."

The original 39 buildings built between 1905 and 1911 were designed by Jarvis Hunt.[1]

The base is like a small city, with its own fire department, Naval Security Force, and public works department.

One of the landmarks of the area is Building 1, also known as the clocktower building. Completed in 1911, the building is made of red brick, and has a tower that stands 300 feet over the third floor of the building. The large parade ground in front of the administration building is named Ross Field.
