The Route of Emperors and Kings extends along the Danube from mediaeval Regensburg, through Passau, Linz, Vienna and Bratislava, to the metropolis of Budapest, linking urban cultural centres, historic treasures and world-class landscapes. This is where the history of Central Europe was written, and this history remains very much a part of life today. From Roman times onwards, kings and queens travelled on and along the Danube with their royal entourages. Over the centuries, this age-old route therefore came to be known as the ‘Route of Emperors and Kings’ – and it has lost none of its appeal to this day.
