Known as Wigwam Village, and then New Garden, this town bears the name of the Ossipee Indians.It was once the site of an Indian stockade fort, designed to protect the tribe from the Mohawks in the west. In 1725, the Indian stockade was destroyed, and then rebuilt by Captain John Lovewell. The new fort was one of the largest in New England. Ossipee would become incorporated in 1785.
The town shares its name with the Ossipee Mountains, a circular mountain range marking the location of an ancient volcanic ring dike, which borders it on the west. Ossipee is a major source of sand and gravel, transported by railroad to Boston, Massachusetts.
