Italy's Trieste spent over five centuries as Austria's great seaport
Trieste sits on a thin sliver of Italy squeezed between the Adriatic and Slovenia, which lies about 8 km away. For more than 500 years it answered to the Habsburgs, growing into the fourth largest city of Austria-Hungary. Today it claims more researchers per head than anywhere else in Europe.
The name probably comes from Tergeste, built on an old word for market, and the site has been lived on since the second millennium BC. Illyrians, then Veneti and the Carni of the Eastern Alps held it before Rome took the town in 177 BC. Julius Caesar named it in his account of the Gallic Wars, Augustus walled it in 33 to 32 BC, and Trajan gave it a theatre. Romans built lavish seaside villas at Barcola, sheltered from the fierce bora wind, and Pliny the Elder praised a local wine that may be today's Prosecco.
In the Middle Ages Trieste competed with Venice for sea trade and paid for it. Venice occupied the city briefly in the 1280s and again from 1368 until 1372. Worn down, Trieste's leading citizens asked Duke Leopold III of Habsburg to take them in, and the act of voluntary submission was signed at Graz on 30 September 1382. The Habsburg link held until 1918, surviving a sack by Emperor Frederick III that locals called the Destruction of Trieste.
Under Vienna in the nineteenth century, Trieste became the empire's most important port and, by the early 1900s, a magnet for writers, musicians and philosophers. After the Second World War it turned into a flashpoint between East and West as the Free Territory of Trieste.
The city still works as a deep-water gateway for northern Italy, Austria, Germany and Central Europe, and is described as the western end of the maritime Silk Road. It stands where Latin, Slavic and Germanic cultures meet, and it has drawn international research bodies since the 1960s. Locals know it by many nicknames, among them City of Wind, City of Coffee and Vienna by the sea. As of 2026 it had 198,622 residents, ranking 17th among Italian cities.
