This event originally ran from 1898 to 1912 and was revived in 1975. and has continued since then featuring horse, oxen and tractor pulls as well as exhibits of animals, flowers, fruits, vegetables and baked goods. In early August, the town also promotes the Orange Volunteer Fireman's Carnival, which raises funds to support the volunteer fire department. Both events are held at the fairgrounds at High Plains Community Center near the center of town.

During the Cold War, Orange served as a location for the permanent deployment of Nike missiles for the defense of Greater New Haven. The former site of the Nike missiles has since served (from the late 1950s onward) as the home of the 103rd Air Control and Warning Squadron, later to become the 103rd Tactical Control Squadron and as it remains today the 103rd Air Control Squadron, a part of the Connecticut Air National Guard^.]
