Discover Trieste
Trieste is a city of remarkable beauty, rich history and vibrant culture. Nestled between the Adriatic Sea and the dramatic Karst cliffs, it offers a unique blend of Italian elegance, Central European charm and stunning nature.
The heart of the city is Piazza Unità d’Italia, one of Europe’s largest sea-facing squares, surrounded by majestic 19th-century architecture.
Piazza Unità d’Italia

Miramare Castle
The white 19th-century residence of Archduke Maximilian of Habsburg, with its park overlooking the Gulf of Trieste.
Faro della Vittoria
The Victory Lighthouse on the Gretta hill, a memorial to those lost at sea, with sweeping views over the city and the Gulf.
Borgo Teresiano
The 18th-century quarter around the Canal Grande, with the Roman Theatre and the historic literary cafés nearby.
Molo Audace & Barcola
The pier for sunset walks and the seafront promenade where Triestini swim and sunbathe in summer.
The Karst
The plateau above the city: the Napoleonic Way panoramic path, the Grotta Gigante cave and the traditional osmize.
A city of coffee
Since gaining free port status in the 18th century, Trieste has been Italy’s coffee capital, a title it proudly holds today as the Mediterranean’s top coffee port. Its historic cafés still preserve a vintage charm, having once welcomed literary legends like James Joyce, Italo Svevo and Umberto Saba.
Don’t miss this local tradition during your stay! Just remember to learn the local lexicon before ordering: a “nero” is an espresso, a “capo in b” is an espresso macchiato in a glass, and a “gocciato” features just a delicate drop of milk foam.
A capital of knowledge
Beyond its historic charm, Trieste is an international powerhouse for research and innovation. With over 30 scientific institutions and a density of 37 researchers per 1,000 inhabitants, the highest in Europe, it welcomes thousands of international scientists each year.
Major global hubs like ICTP – International Centre for Theoretical Physics, SISSA – International School for Advanced Studies, OGS – National Institute of Oceanography and Experimental Geophysics, the Elettra Sincrotrone light laboratory and the WWF Marine Reserve in Miramare make Trieste a true capital of knowledge.
