Military urbanism is referred within this research as a city-design approach, through which urban fabrics finds its origins from the organization of military architectural systems of the patron state entities. This approach would be continued in contemporary times as cultural urbanism, which is to say that the city’s planning identity would be derived from its military planning origins. Their urban blueprints, rooted in indigenous ethos, were crafted within the confines of a fortified town model. Thrissur and Thiruvananthapuram, products of the Kochi and Thiruvithamkur Empires, respectively, served as seats of power for their ruling elites. The nomenclature of key locations within these cities, such as “East Fort” and “West Fort,” signifies the existence of a military planning schemes that governed the planned development of quarters and urban spaces. Employing tools like geographic information systems, historical records, and maps, alongside toponymy, this study explores the narrative of city design and urbanism shaped by military imperatives. By cross-referencing these historical foundations with the contemporary identities of present-day Thrissur and Thiruvananthapuram, an evaluative lens is applied to discern the enduring impact of military-driven architecture on the operational framework of these cities. This exploration facilitates an understanding of how military city design provided a robust foundation, allowing for the expression of cultural vibrancy within the urban milieu, challenging perceptions of obsolescence in military architecture.
