- Luxembourg’s Belval district becomes a smart city testbed using AI, 5G and edge computing.
- Smart spires project enables live urban experimentation in sustainability, traffic, and public engagement.
What happened
A new initiative named Smart spires is transforming Luxembourg’s Belval district into a large-scale smart city living lab, combining 5G, AI and edge computing to test and demonstrate real-time urban innovations. The project, launched by Luxembourg Institute of Science and Technology (LIST) and supported by various partners, enables the public and private sector to trial smart city solutions in a live environment.
Belval now hosts sensors, edge nodes and data processing infrastructure across public areas, with applications ranging from traffic monitoring and environmental sensing to interactive citizen displays. According to LIST, this “open-air test zone” is designed to shorten innovation cycles by allowing companies, researchers and municipalities to develop and iterate on connected systems in a dynamic setting. The site includes digital twins, real-time dashboards, and communication layers built atop high-bandwidth 5G infrastructure. The aim is to create a replicable model for other European cities.

Why it’s important
Smart spires reflects a growing movement in Europe towards data-driven urban development that relies on live experimentation rather than isolated lab research. The project positions Belval not just as a test zone but as a template for future edge-enabled smart cities. With local authorities and citizens engaging directly with emerging technologies, the initiative challenges traditional top-down urban planning models.
The project also aligns with EU ambitions under programmers like Horizon Europe, which fund testbeds for energy efficiency, traffic optimization, and AI governance. Real-world deployments like this can address long-standing gaps between research and implementation. As noted by project leaders, direct involvement of citizens and municipal services ensures transparency and relevance.
However, such initiatives also raise questions about data privacy, digital equity, and the scalability of tech-heavy solutions in smaller urban areas. While Belval benefits from Luxembourg’s investment in innovation, replicating these models in less connected regions may prove challenging without broader regulatory frameworks and infrastructure investment.
