Joint Base Cape Cod, state-designated joint base in Barnstable County, Massachusetts, United States
Joint Base Cape Cod is a large military installation covering around 22,000 acres across four towns in Massachusetts. The northern portion serves mainly for training exercises, while the southern area holds support buildings, hangars, simulators, and housing for Coast Guard families.
The site began as a training ground for the National Guard in the early 1900s and was later used by the U.S. Army during the 1940s to prepare soldiers for World War II. After the war, the Air Force took over and operated it as Otis Air Force Base before the current multi-branch arrangement developed.
The name reflects how different military branches share this space and work side by side. Visitors notice the steady presence of personnel in uniform and active operations that define daily life here.
The site sits above an underground water source that supplies drinking water to surrounding towns, so public access is limited for security and environmental protection reasons. Check ahead for any visitor information and access requirements before planning a visit.
The base is home to the only National Cemetery in New England, where veterans are honored with graves and memorial services. This cemetery serves the entire region and stands as a place of remembrance for military service members.
