Context

Our verdict

Trieste, port city in the north-east of Italy on the Slovenian border: 200,000 inhabitants at the bottom of the Adriatic , capital of Friuli-Venezia Giulia. Unique atmosphere mix of Italo-Slavic-Austrian (the city only became Italian in 1918 after remaining Austrian for 500 years 1382-1918, main port of the Austro-Hungarian empire for the Mediterranean).
