The Governor Wilson Lumpkin House, also known as the Rock House, is located at on Cedar Street (Tax Parcel No. 17-1) in the middle of the University of Georgia's south campus.
 

Built high upon Cedar Hill looking northward over the Tanyard Creek ravine, and today's Sanford Stadium, this two-story house possesses a two-over-two room, central hall plan. Built of stone collected around the property and cut and dressed on site, the dwelling stands on two-foot-thick basement walls. On the north elevation a steep flight of stone steps leads to a small one-story porch with simple wooden post supports. Revealing the influence of the Greek Revival style, a transom and sidelights accent the central entrance. An adaptation of a Palladian window, featuring the traditional sidelights but omitting the light above the center window, appears above the doorway. Stone lintels embellish the remaining windows.

Notable Georgian, Indian Commissioner, Congressman, and Governor, Wilson Lumpkin purchased the first parcel of what became an almost 1000-acre plantation south of Athens on the "road to Watkinsville." By 1842 his farm was enclosed within the city limits. He designed his residence to resemble the old millhouse at Cedar Shoals, and engaged Edward Lilley of Ireland to do the stonework, David Demorist of New Jersey for the woodwork, C. G. Oliver of England for the painting, and a Mr. Williams of New York City for the plastering. Construction began in 1842 and ended in 1844. Governor Lumpkin was the older brother of Joseph Henry Lumpkin and the father of Martha Atlanta Lumpkin Compton, for whom a strategic junction on the Western and Atlantic Railroad was first named Marthasville and later Atlanta. When his daughter inherited the plantation, she gradually sold off acreage to the university as it expanded southward. When the university purchased the remaining acreage including the house in 1907, she insisted on a provision that the house be kept intact or the property would revert to her heirs. This protective clause insured the preservation of the dwelling, which has been used as a classroom, branch library, computer center, and headquarters for the Institute of Ecology. The College of Agricultural and Environmental Sciences' academic unit of the Cooperative Extension Service currently occupies the building.

The Governor Wilson Lumpkin House is listed on the National Register of Historic Places (March 16, 1972).
