The gallery space along the ramp is lit by means of a skylight dome and small windows that follow the upward spiral. Wright has developed the concept of an open well and spiral shape in his earlier works as can be seen in Appendix 1. Appendix 2 analyzes the 5th Avenue faade of the Guggenheim. The Guggenheim was commissioned to house Solomon R. Guggenheim's collection of non-objective art. However the museum has proved problematic for curators and visitors alike.
Large paintings are impossible to hang because of the curved walls and low ceiling.
The gallery-goer is given little freedom to wonder from painting to painting and has to stand on an incline, and view paintings that are slanted away from him. Because of its sculpture-like form and sheer magnificence the Guggenheim itself dominates any display of paintings or sculptures housed in it. The inherent difficulty of Wright's design propelled the Guggenheim to renovate and add-on to Wright's work in 1992. Gwathney and Siegel have added extra gallery space allowing the main ramp to stand alone in its entire splendor. The Guggenheim is the culmination of Frank Lloyd Wright's principles of organic architecture.
