Designed and constructed from 1815 to 1821 by Irish craftsmen Thomas Battersby and John Hoy, this house was built by Greeneville's first postmaster, William Dickson, for his daughter, Catharine, Mrs. Alexander Williams. Visitors included Marquis de LaFayette, Presidents Jackson and Polk, Henry Clay, David Crockett, and Frances Hodgsen Burnett. It served as headquarters for both Confederate and Union officers. Confederate General John Hunt Morgan spent his last night here before being killed in the garden on September 4, 1864.
