A large shopping centre covering more than 160,000 square metres, Médiacité was built between 2007 and 2009. Its striking feature is the roof designed by Ron Arad, which runs for 360 metres over the mall. Consisting of transparent and red ETFE (a fluorine-based plastic) ‘cushions’, the roof looks like a reptile’s skin when seen from the air. Liège’s iceskating rink – the only Olympic-size skating rink in Wallonia – is located at one end of the gallery; it was completed in 2012. Finally, alongside the entrance to Médiacité, the Média Rives building houses the French-speaking Belgian Radio and TV (RTBF) station. Média Rives also has a 1,200 square metres studio, the biggest in the Wallonia-Brussels Federation.
