The scenic vistas from the 30th floor Concourse Center otherwise known as the Queen building, take in downtown Atlanta, Stone Mountain and Kennesaw Mountain. Recently renovated, the center can be found where the I-285 and GA 400 meet in a 63-acre landmark mixed-use complex in the upscale northern suburban Perimeter district. Financial services, law firms and IT services companies are all in the vicinity, along with many of Atlanta's main attractions - the world's largest aquarium, theatres, hotels and shops. The center has many corporate neighbors, and a high proportion of medical facilities. Perimeter employs more than 100,000 employees - making it the biggest employer district in the region. There are 4,000 businesses here and 125 companies have 100 or more employees. The Concourse facility offers daily shuttles to the Marta train station located nearby.
