Trinity services on Mackinac Island date from 1837, when a Bishop preached in the Mission Church. For many years the congregation met in the post Chapel at Fort Mackinac and in the Court House. In 1873, a parish was organized and in 1882 this church building was constructed. Its furnishings include an altar of hand-carved walnut and two chancel chairs made by soldiers at the fort.
