As European leaders prepare to celebrate the foundation of the European Union in Rome 60 years ago, Greenpeace activists kicked off three days of public demonstrations and events by displaying a giant 100m2 banner from Pincio overlooking the centre of the ancient city.

The banner, depicting a fluttering EU flag revealing a solar panel, read: “After 60 years: a better Europe to save the climate.” The activists later delivered the banner to the Italian presidential palace, where the Treaty of Rome was originally signed on 25 March 1957.
