Fortification as a concept plays an important role in critical discourse regarding (city) development. Fortification represents a condition, where a strong enough "medium"exist in between two spaces. Fortification also gives a strong meaning to add ones forces, to make a particular (mostly designed) space to be stronger, creating a sort of comfort environment. Fortifications could be meta-physical, where it solidifies as an interface, a borderline, the boundary itself. This paper brings discourse into interpretation of fortification, from prior related knowledge to understand the concept of it from each individual within the city structure, which affects the values (actions and behaviors) of the residents differently. The context of urbanism to be discussed refers to studies of urbanity, architecture and urban design. The discussion ranges from the most relevant initial study, significant to the topic built on the presence of fortification, the context of urbanism, space and plot (urban space), and also the boundaries and scope of the research topic. The author sees a phenomenon related to the development of real-estate in Indonesia in the form of the flourishing gated community settlements and exclusive high density urban business entities. This is contrary to the principles of New Urbanism that views accessibility and openness as one of many principles in planning neighborhoods. This is what builds the research novelty and becomes an important element in formulating the state of the art of the author's research plan.
