Naval Station Great Lakes

Naval Station Great Lakes (NAVSTA Great Lakes) is the home of the United States Navy's only current boot camp, located near North Chicago, in Lake County, Illinois, along Lake Michigan. Important tenant commands include the Recruit Training Command, Training Support Center and Navy Talent Acquisition Group Great Lakes. Naval Station Great Lakes is the 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 69 mi (111 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". It is also referred to as "second boot camp" for those attending Training Support Command.

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

The base functions similarly to a small city, with its own fire department, Naval Security Forces (Police), 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 over the third floor of the building. It faces a large ceremonial parade ground, Ross Field.
