Wilhelmsburg is Europe's largest river island, in the very middle of Hamburg. A district undergoing radical change, its diversity is just waiting to be discovered. Between the fringes of the port and the motorway, late-nineteenth-century neighbourhoods and old village centres, nature reserves and protected landscapes, this has been the location for the International Building Exhibition IBA Hamburg since late 2006. In 2013 the IBA will present over sixty projects: the future of the city on the Hamburg Elbe Islands and in Harburg's Upriver Port. How will we live, work, and learn in the future? Where will our energy come from? How will we tackle the challenges of climate change and international urban communities? How can cities grow in a sustainable way, and where will they expand to? The IBA answers all of these questions and invites visitors to discover the city of tomorrow using this guide.
