Armed with his trusty copy of Bradshaw, Michael Portillo explores the former domain of the Habsburg monarchs, beginning in the Hungarian capital Budapest. He then travels to Austria via Bratislava in Slovakia, and in Vienna he immerses himself in pre-First World War decadence. From there he heads to Salzburg, before going on to the Salzkammergut region to visit the emperor's Austrian summer residence at Bad Ischl, where in 1914 Franz Joseph I signed a declaration that changed the course of European history.
