Diegem, 26 March 2026 — LCL Data Centers announces the opening of its newest and largest data center in Diegem. This major expansion reinforces LCL’s position as a 100% Belgian and fully European player, and forms a crucial building block for a sovereign, secure, and future‑proof data and AI infrastructure in Belgium and Europe.

The new data center in Diegem meets the highest standards in terms of security, reliability, and sustainability. It supports the growing need for capacity for critical data, cloud connectivity, and AI applications, and thus plays a key role in Belgium’s digital autonomy.

Local control over data flows has become a strategic requirement today for many organizations, including government services, hospitals, and financial institutions. As a fully Belgian company, LCL demonstrates that digital sovereignty is not a theoretical concept but a reality already being built today. Thanks to this expansion, sensitive and strategic data can remain within the Belgian and European legal space, under the management of an independent, local operator.

Laurens van Reijen, founder and CEO of LCL Data Centers: “With this new location, we are taking an important next step in building a truly Belgian and European digital backbone. This data center is designed for the future — AI‑ready, sustainable, and built to protect the most critical data. Our role as a 100% Belgian player gives us a unique responsibility: ensuring that strategic data can remain safe, independent, and close to home. This is only the beginning of what we can and want to achieve for Belgium.”

Built for an AI‑driven and sustainable future

The new site is designed with future technological evolutions in mind. It supports high‑density environments, is ready for AI workloads, and was built with a strong focus on sustainability, including solar panels installed on the façade.

Key features:

• Maximum reliability and uptime, following the highest quality standards
• Infrastructure designed for AI applications
• Sustainable architecture supporting LCL’s innovation and environmental strategy
• Full compliance with Belgian and European regulations

A new “skAI‑line”: where technology and Belgian art reinforce each other

The opening of the data center is accompanied by the installation of a unique artwork by Luk Van Soom, who previously contributed to shaping the Brussels skyline with “In The Cloud.” His new creation becomes a striking new silhouette along the Brussels Ring — a “skAI‑line” combining technology and art. On the roof, his artwork “De Wolk” (“The Cloud”), a floating cloud atop the five‑story data center, will be an eye‑catcher for passers‑by.

“Data centers are usually buildings that are everywhere yet invisible. Still, they carry the invisible infrastructure of our modern world,” Van Soom explains. “In a sense, data centers are the cathedrals of the 21st century. I wanted to explore the tension between the intangible nature of ‘the cloud’ and the very tangible, concrete structure of a data center in a physical, poetic way. A cloud is something you can see, but never truly touch.”

Designers René Pijnenburg and Béla Zsigmond, along with Chief Architect Luc De Hovre (With20), also contributed to the site, adding cultural value alongside its technological significance.
