This thesis proposes an urban intervention to create a new type of public space in the city of Shanghai. It investigates the historical evolution of the public spaces in the city and concludes that a new type of public space without prescribed functions and boundary restrictions should be introduced. The Space of Appearance is a prototype of such that is designed for the people to appear to each other rather than to the physical space. In this prototype, a collection of nine follies, with a nine-point organization, is inserted into a selected urban field. The dispersed yet organized nature of the nine follies brings the dynamic formation of the crowds. A temporal dimension is embedded in the completeness of the nine follies, allowing for an ever-changing definition of the space given by the people.
