OM Liège

OM Liège is a 1,700-capacity concert complex in Seraing, on the edge of Liège. Its defining feature is the building itself: the former Salle des fêtes d’Ougrée-Marihaye, a 1948 workers’ banquet hall created for the Cockerill industrial community. The restored site keeps that connection to the Meuse valley’s steelmaking landscape while operating as a three-room home for amplified shows and large-format events.

A workers’ hall becomes a stage

Architect Georges Dedoyard designed the original hall in 1948 for Ougrée-Marihaye; it began serving company celebrations in the early 1950s. Its long horizontal lines, rounded forms and corner windows place it within a late Art Deco, streamlined architectural language, giving the concert setting a physical identity beyond a standard black-box room. Industrial restructuring gradually emptied the hall, and the City of Seraing bought it from ArcelorMittal in 2010 as part of a cultural redevelopment plan.

After renovation, OM opened to the public on October 4, 2023, with local collective Oootoko playing the inaugural night. That debut put a new music operation inside a hall that had spent decades as a workplace gathering space, then years awaiting its next use.

The room today

Concert programming is handled by Festiv@ Liège, the team behind Les Ardentes, Reflektor and Jazz à Liège, and the schedule ranges across folk, indie, R&B and pop. The adaptable complex has rooms for 300, 500 and 1,700 people; Trasenster, the largest, includes a private balcony that adds an elevated sightline option. Several bar areas operate around shows, with the venue also offering restaurant and food-truck service on concert evenings.
