This article focuses on the potential of the Galata Bridge as a “polyvalence” space for gathering urban crowds and enabling arbitrary relations in İstanbul. The bridge is a mirror for modern daily interactions with the bridge in terms of superimposition, arbitrary and fragmentary urban life. Composed of multiple layers of space on different levels (floors), the cultural values of the bridge extend a mere functional approach. Polyvalence, a term coined by Herman Hertzberger, can be a tool for expressing multiple relations in urban space and extends a mere functional space where diversities fuse into each other. In this context, the bridge can be defined as a spontaneous organizational space that produces its own entity, in which human actions and activities overlap. Thus, the bridge enables the development of arbitrary relationships in Istanbul.
