Langdon Hall is a building on the campus of Auburn University in Auburn, Alabama, United States. Built in the Greek Revival style in 1846 as the chapel for the Auburn Female College (today Auburn High School) and moved to the Auburn University campus in 1883, Langdon Hall is the oldest building in the city of Auburn, and today houses an auditorium and office space for Auburn University staff. Before the Civil War, Langdon Hall served as the location for a series of debates on the question of Southern secession, involving William Lowndes Yancey, Alexander Stephens, Benjamin Harvey Hill, and Robert Toombs. Langdon Hall is named for Charles Carter Langdon, a former mayor of Mobile, Alabama, Alabama Secretary of State, and a trustee of Auburn University from 1872–1889.
