If it weren’t for the blast furnaces and a few other historical relics from ArcelorMittal, you wouldn’t know that Belval was ever an industrial site. In the heart of the ‘Cité des Sciences’, the architectural firm Valentiny hvp has transformed an old 110 metre long ‘Möllerhalle’ into a contemporary university library, which opened its doors at the start of academic year 2018-2019. The original steel supporting structure of the building was preserved, treated and reinforced so that the complex could be given a new facade and composite roof. The unique synergy between old and new gave rise to a masterpiece that earned the project both the jury and audience prizes in the Steel Construction Competition 2019.
