This private archive and exhibit complex, with thousands of historic photos, documents, portraits, and books, is one of the finest research centers in the South. It occupies the 19th-century townhouse of General Kemper Williams and the 1792 Merieult House. Changing exhibits focus on various aspects of local history. Architecture, history, and house tours are offered several times daily, and a museum shop sells books, prints, and gifts. The Williams Research Center addition, at 410 Chartres Street, hosts additional free exhibits.
