One of America's finest examples of Federal architecture, this 1808 house was completed by Nathaniel Russell, one of Charleston's richest merchants. It is celebrated architecturally for its "free-flying" staircase, spiraling unsupported for three floors. The staircase's elliptical shape is repeated throughout the house. The interiors are ornate with period furnishings, especially the elegant music room with its golden harp and neoclassical-style sofa. The house is accessible to visitors only on guided tours.
