Vallitsevilla

Vallitsevilla is a term used in urban planning discourse and speculative fiction to designate a valley-centered urban concept surrounding the city of Seville, Spain. The name blends a reference to valleys with the well-known city of Sevilla (Seville), signaling a focus on low-lying, water-rich landscapes and their adaptability to dense, multimodal urban life. As a concept rather than a formal place, vallitsevilla functions as a framework for design principles rather than a single jurisdiction.

Geography and design theory

The concept envisions a linear, valley-oriented growth corridor along the Guadalquivir basin, emphasizing flood resilience, green corridors, and transit-oriented development. Core ideas include integrated water management, permeable urban surfaces, and a network of canals, parks, and pedestrian routes connected by light rail and cycling infrastructure. Buildings are imagined with mixed uses, climate-responsive facades, and modular, resilient construction to cope with variable precipitation and heat.

History and usage

Vallitsevilla emerged in planning debates and speculative literature in the 2010s as a model for sustainable growth in valley basins near major cities. In academic contexts it is used to illustrate how cities can balance flood risk, ecological values, and high-density living. In fiction, it appears as a setting exploring adaptation to climate change and interregional connectivity.

Status

There is no administrative entity named vallitsevilla. It remains a theoretical concept and fictional construct used to discuss valley-based urbanism around Seville. See also: valley city concepts, Seville urban planning, water-sensitive urban design.
