Prismanilla

Prismanilla is a fictional city-state created for use in urban planning, speculative fiction, and educational exercises. In most renderings, it is a coastal metropolis on the Prism Archipelago, noted for its mixed-use districts, dense urban core, and a focus on sustainable development.

The archipelago comprises a main island and several smaller islets, with hills and a central harbor. The climate is temperate maritime, featuring mild summers and wet winters.

In the fictional chronology, Prismanilla originated as a free port in the early modern period, later developed into a trading hub, and adopted a constitutional framework with a unicameral city council and an executive governor. The governance model emphasizes urban planning, climate resilience, and transparent data.

The economy is diversified, with maritime logistics, finance, information technology, and creative industries playing major roles. The port handles cargo and cruise traffic, while energy comes from solar, wind, and tidal sources. Public transit is extensive and multimodal.

The population is described as multilingual and culturally diverse, with institutions that support public education and research. Notable public spaces include Lumen Park and Prism Square, and an annual light festival appears in several depictions. The exact attributes of Prismanilla vary across sources since it is a fictional construct.
