The Royal Philharmonic Orchestra of Liège opens its doors for a two-day festival designed entirely for young audiences. Saturday welcomes babies and toddlers (6 months to 5 years) with gentle musical storytelling and sensory workshops, while Sunday shifts to older kids (4–12 years) with orchestral performances, playful behind-the-scenes discoveries, and family-friendly animations. It’s a rare chance to experience a world-class concert hall through a child’s eyes—and ears.
