Trieste is a city of about 200000 inhabitants on the coast of northeastern Italy. It is located on a strip of Italian territory, only a few km from the border to Slovenia. Trieste has a long history dating back to the second millenium BC. It submitted to Austrian rule in 1382 becoming over the time one of the most important cities, the main port and an important trading hub of the Austro-Hungarian empire. After World War I Trieste passed to Italy. Due to its long and prosperous history Trieste has an impressive historic core centered around Piazza dell'Unità d'Italia and Canale Grande. Here there are countless buildings, most in neoclassical style and most built during the Habsburg period. The San Giusto castle overlooks from the top of a hill the city of Trieste.
