Leyden House, Greek Revival mansion on Peachtree Street, Atlanta, US

Leyden House was a Greek Revival mansion at 124 Peachtree Street NE in Atlanta, designed by architect John Boutell. It had Ionic columns at the front and sides, an unusually grand scale for antebellum Atlanta, and stood between Cain (now Andrew Young International Blvd.) and Ellis streets.

Built in 1858, the structure served as headquarters for Major General George H. Thomas and his Army of the Cumberland during the Civil War. The building was demolished in 1913 when Asa G. Candler acquired the property for commercial development.

Austin Leyden, who co-founded the Atlanta Machine Works in 1848, lived here with his family; the house stood at 124 Peachtree Street NE, between Cain (now Andrew Young International Blvd.) and Ellis streets. The site later held the Davison's department store flagship, the 180 Peachtree Building, used mostly as a data center as of 2012.

The original Ionic columns from the house were preserved after the building's demolition and remain visible today at the Old Woodberry School Building site in Ansley Park. Visitors can view these architectural elements at 149 Peachtree Circle.
