This is a stunning piece of architecture by Frank Lloyd Wright. Much of his work was organic and based on nature. In the case of the Guggenheim Museum, the organic, curved shape is a sharp contrast to the Manhatten buildings around it. This makes the building stand out and shows off it's unique design.
The spiral look of the outside continues on the inside. There has been some criticism that the building overshadows the artworks displayed in the museum. I do not really agree with this as I think the building is a piece of art in it's own right. Also, even though it is an impressive building, it is still quite simple and white, enabling the colourful pieces of art stand out against the plain walls.
Another criticism the museum has had is that even though there is a large skylight, the walls where the paintings hang are cast into shadow due to the design of the building. This means the paintings are lit artificially. I do not think this is a bad thing. It means that the artwork can be lit in a way that best show off the work.
