Vienna to Trieste
In Vienna, Michael Portillo encounters a pre-Cold War spy and learns about the concert that caused a riot in 1913. He then travels the Habsburg imperial line across the Semmering Pass, a line blasted through the Alps. In Graz, the former politician ventures underground at the Lurgrotte Caves to find out about a famous rescue operation of the past, then in Slovenia discovers how an earthquake in Ljubljana prompted its citizens to assert their national identity in architecture and art. Arriving in the Italian port of Trieste, Michael savours the imported coffee that fuelled a cafe culture.
