Buckhead is the uptown commercial and residential district of the city of Atlanta, Georgia, comprising approximately the northernmost fifth of the city. Buckhead is the third largest business district within the Atlanta city limits, behind Downtown and Midtown, and a major commercial and financial center of the Southeast. Buckhead is anchored by a core of high-rise office buildings, hotels, shopping centers, restaurants and condominiums centered around the intersection of Peachtree Road and Piedmont Road near Georgia State Route 400, the Buckhead MARTA station, and Lenox Square. In 1838, Henry Irby purchased 202 1/2 acres surrounding the present intersection of Peachtree, Roswell, and West Paces Ferry roads from Daniel Johnson for $650. Irby subsequently established a general store and tavern at the northwest corner of the intersection. The name "Buckhead" comes from a story that Irby killed a large buck deer and placed the head in a prominent location. Prior to this, the settlement was called Irbyville. By the late 1800s, Buckhead had become a rural vacation spot for wealthy Atlantans. In the 1890s, Buckhead was rechristened Atlanta Heights but by the 1920s it was again "Buckhead". Buckhead remained dominated by country estates until after World War I, when many of Atlanta's wealthy began building mansions among the area's rolling hills. Simultaneously, a number of Black enclaves began popping up in Buckhead, following events like the 1906 Atlanta race riot and the Great Atlanta fire of 1917, which drove black residents from the city center. Predominantly black neighborhoods within Buckhead included Johnsontown, Piney Grove, Savagetown, and Macedonia Park. Despite the stock market crash of 1929, lavish mansions were still constructed in Buckhead throughout the Great Depression. In 1930, Henry Aaron Alexander built one of the largest homes on Peachtree Road, a house with 33 rooms and 13 bathrooms. During the mid-1940s, Fulton County decided to acquire the land comprising Macedonia Park to build what is now Frankie Allen Park.
