Marsh-Warthen House, Greek Revival house museum in LaFayette, United States.

The Marsh-Warthen House is a two-story Georgian-plan house with a central hall, four rooms over four rooms, a low hipped roof, and a south porch with square Doric columns topped by a second-story balcony. Spencer Stewart Marsh built it in 1836; a two-story northeast wing with kitchen and servants' quarters was added around 1900, and roof dormers followed in the early 20th century.

Spencer Marsh, born in Chatham County, North Carolina, in 1799, built the house in 1836 after moving to the settlement soon renamed La Fayette. In 1845 he co-founded the Trion Factory Company, the first cotton mill in Northwest Georgia, on the Chattooga River. During the Civil War the family left for Cassville, and Union troops occupied the house during the Battle of LaFayette in June 1864.

Spencer and Ruth Marsh raised their six children here and sometimes rented rooms to boys attending Chattooga Academy, the brick school just south of the house. One boarder was John B. Gordon, later a Confederate general, Georgia governor and U.S. senator.

The house is easily accessible within the town and offers guided tours for visitors who want to learn more about its history and architecture. It is advisable to check current opening hours in advance to plan a visit properly.

The house was a focal point during the Battle of LaFayette in June 1864, when Union troops occupied it while the Marsh family was away in Cassville. The family returned after the war to find all their furniture and household items had been taken.
