Vienna From a Different Angle

The Vienna Tourist Board is building a 21-metre-high wall – the biggest temporary structure ever built in Trafalgar Square – for a series of acrobatics performances (daily 1pm, 3.30pm, 5.30pm, 7pm) and aerial displays celebrating Viennese culture. In between shows, there is a chance to take a 'horizontal stroll' down the wall (wearing a specially developed climbing harness).
