Austin Hall, the original building of Austin College, erected in 1851 and used continuously for educational purposes by Austin College to 1876, by a private academy from 1876 to 1879, and by Sam Houston State University from 1879.

The Presbyterian Church established Austin College in Huntsville in 1849 and erected this structure in 1851-52. Austin College moved to Sherman in 1876, and in 1879 this building was deeded to the state for use by the newly-established Sam Houston Normal Institute (now Sam Houston State University).  The Greek revival-era building features a three-bay front facade, two-story portico, and Doric columns. A third floor, added in 1882, was removed in 1926-27.
