In 1909, Rev. William Worthington decided to locate a Reformed Church College in Jackson County, KY. His vision was for some sort of technical school to help promote his vision of "complete living for the mountain people." The beautiful property with its rolling hills and large meadows was purchased and the Annville Institute started that Fall and has served the community in multiple facets ever since. Although the Annville Institute no longer operates as a school, it still benefits the community through its numerous outreach program and facilities.

Lincoln Hall served as the main classroom for the Annville Institute. The original Lincoln Hall was destroyed by fire in 1921. The present building was built in 1922 and 1923 on the foundation of the original building. After the Institute ceased its educational operations in 1978, the building has primarily served as a community center, with no true purpose.
