Peachtree Center is a district located in Downtown Atlanta, Georgia. Most of the structures that make up the district were designed by Atlanta architect John C. Portman, Jr.. A defining feature of the Peachtree Center is a network of enclosed pedestrian sky bridges suspended above the street-level, which have garnered criticism for discouraging pedestrian street life. The district is served by the Peachtree Center MARTA station, providing access to rapid transit.
