Trieste

Trieste is a city and seaport in northeast Italy. It is the capital and largest city of the autonomous region of Friuli-Venezia Giulia, as well as of the regional decentralization entity of Trieste. As of 2025, it has a population of 198,668. Trieste is located at the head of the Gulf of Trieste, on a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia; Slovenia lies close, at approximately 8 km (5 mi) east and 10–15 km (6–9 mi) southeast of the city, while Croatia is about 30 km (19 mi) to the south of the city. The city has a long coastline and is surrounded by grassland, forest, and karstic areas. Trieste belonged, as Triest, to the Habsburg monarchy from 1382 until 1918. In the 19th century, the monarchy was one of the Great Powers of Europe and Trieste was its most important seaport. As a prosperous trading hub in the Mediterranean region, Trieste grew to become the fourth largest city of the Austro-Hungarian Empire (after Vienna, Budapest, and Prague).
