Public art is an equal, free and shared values cultural practice pattern which is built on public foundation. With the connection between public art and architecture, the space context can be made which contains form, space and style. Architecture spaces can be divided into outside-form parts and inside-function parts. In the matters of outside-form parts, most architecture spaces display sculpture-style form connections. While in the matters of inside-function parts, the combination of public art and space presents the regeneration of space vision and space sight without consideration of functional factors.
