This article introduces "Virtuopolis", an innovative concept of a digital city designed around the principles of virtue and excellence across the social, cultural, intellectual, and ethical dimensions. Unlike traditional digital twins, Virtuopolis aims to replicate not only the physical aspects of a city but also its cultural, emotional, and symbolic dimensions. The three-layer framework of Virtuopolis comprises "The Things", focusing on digitizing and preserving cultural heritage; "The Flows", capturing dynamic cultural interactions; and "The Experiences", measuring the impact of cultural experiences on personal and social life. By leveraging advanced computational methods and network theory, Virtuopolis provides a platform for urban planning experimentation, fostering collaboration among diverse stakeholders and enhancing the liveability of cities through the integration of cultural and artistic values.
