The architecture here is unique! No tunnellining was installed in this station. The architects and civil engineers decided to leave the rugged gneiss rock walls.
MARTA's best-looking station, bar-none. Be sure you know which side to exit on; the north and south exits are a long ways apart. (Most of the hotels, including Dragon*Con hotels, are to the north.)
The deepest station in the MARTA system is the Peachtree Center Station which is located in a hard-rock tunnel, 120 feet (36 meters) beneath downtown Atlanta!
Exit Harris/Peachtree West, turn right just outside the exit for the glass-covered walkway into AmericasMart -- air conditioned access to Westin and through Westin to Marriott, Hampton Inn, etc.
