Day 1 — Belval: a first loop among the blast furnaces and Rockhal
🚶 Start at Belval-Université station: in 3–5 minutes you’ll reach the Rockhal concert complex—one of the icons of Belval’s new life. Then head to the “Hauts Fourneaux” blast-furnace terrace: monumental silhouettes and viewing platforms at the level of the technical decks immediately set the right tone—here the old steelmaking framework has become a stage for science, music, and urban life. Cement your feel for the district with a short loop along Boulevard Porte de France and on to Maison du Savoir—the horizontal “bridge-building” and the university tower form the central axis of the “city of knowledge.” In the evening, return to Rockhal Square: lights, reflections in metal, and open spaces make sunset especially cinematic.
