Perry-Rainey Institute was founded in 1892 by the Mulberry Baptist Assn. at Appalachee Baptist Church in Auburn. Its predecessors were Harmony Grove Academy, Mulberry High School, and Perry-Rainey College. It was named for Reverend Hiram Rainey and Mrs. W.T. Perry, who were donors. The institute opened in 1893, was chartered in 1894, and held its first graduation in 1896. In 1915 it was sold to the Christian Church and became Southeastern Christian College until 1924. In 1928 it was sold to Barrow County, and the Administrative Building became Auburn-Consolidated School. The building was torn down in 1958, and only the girls dormitory remains, owned by R and R Manufacturing Co.
