The Skopje project marked a shift in Tange’s work, where urban structures took on deeper symbolic meaning. Unlike his earlier schemes, Skopje’s City Gate and City Wall were not just functional elements but metaphors that shaped the city's identity. The City Wall, envisioned as an elevated megastructure, housed government offices, commercial centers, and cultural institutions along a continuous pedestrian-friendly axis. This elevated platform separated vehicular traffic from pedestrian movement, improving urban connectivity and accessibility in a modernist and modular city core. The City Gate was Skopje’s main transportation center, incorporating rail, highways, buses, and pedestrian movement in a multi-level structure. Inspired by Le Corbusier’s Ville Contemporaine, it housed the train station underground, with parking decks, transit terminals, and pedestrian zones layered above. This transportation center connected directly to the City Gate, a business district featuring office towers, cultural institutions, shops, and restaurants—all linked by elevated motorways to form the city’s main axis. Skopje’s linear urban structure extended from this terminal, linking the central business district to the civic square as the city’s backbone. In line with Tange’s earlier projects, the plan introduced a monumental scale and a three-dimensional transport network that organized movement across different levels. Buildings in both the City Gate and City Wall followed a modular design, combining cylindrical towers for circulation and services with horizontal volumes for residential and commercial uses, a concept first developed in Tange’s Kofu prototype. Public space and urban identity were key to the plan, with the Vardar River acting as a civic spine. Tange incorporated green corridors, riverfront parks, and open plazas for accessibility and social interaction. His modernist approach favored exposed concrete, geometric forms, and car-free public plazas, espousing socialist ideals of collective space and Metabolic urbanism, where pedestrian connectivity and monumental infrastructure coexisted to shape a flexible city.
