John Hay Air Base

John Hay Air Base, more commonly known as Camp John Hay, was a major hill station located near Baguio City used for rest and recreation for personnel and dependents of the United States Armed Forces in the Philippines as well as Department of Defense employees and their dependents. It was last run by the United States Air Force. While officially designated a communications station, the facility was mainly used for rest and recreation. The facility housed The American Residence as well as Broadcasting facilities of the Voice of America.

John Hay Air Base was established on October 25, 1903 after President Theodore Roosevelt signed an executive order setting aside land in Benguet for a military reservation under the United States Army. The reservation was named after Roosevelt's Secretary of State, John Milton Hay. For a time, elements of the 1st Battalion of the Philippine Division's 43d Infantry Regiment (PS) was stationed here. Prior to World War II, a number of buildings had been constructed on base, including a U.S. Army Hospital and the summer residence of the Governor-General of the Philippines, later to be known as The American Residence, which is now used as the summer house of the United States Ambassador to the Philippines.
