Trieste is surrounded by a picturesque karst plateau. Border town, is a mixture of cultures Italian, Austro-Hungarian and Slavic. The main monuments in the historical center are the Arco Riccardo and Roman theater, built by Emperor Trajan in the first and second centuries almost entirely of stone. In the center of the city there is the Castle of St. George near the famous Cathedral of San Giusto, the most important religious building in the city. Not to forget the Piazza Unification of Italy, surrounded on three sides by neoclassical buildings, and the fourth side of the sea. It also signals the imposing Victory Lighthouse that stands on the hill Gretta, monument dedicated to the fallen of the First World War. Important writers such as Rainer Maria Rilke, James Joyce and Italo Svevo were then fascinated by the historic cafés that once were places of meeting place for scholars and writers, which together with the port and the impressive Art Nouveau architecture, make the city mysterious and fascinating . As for the attractions located outside the center of the city, they are accessible via the historic “Tram of Opicina”, in operation since 1902. In the rest of the province there are many interesting destinations to start from the seaside village of Muggia in Venetian style with a quaint harbor, a magnificent cathedral and valuable buildings including the castle, in addition to the archaeological park of Muggia Vecchia. The town of Duino, boasts a castle built on a rock overlooking the sea karst, surrounded by a large park with terraces and boulevards. A few kilometers from the sea the Rosandra Valley, is a very special landscape where we recommend the walk that starts from the village of Bagnoli della Rosandra and along the first stream and then climbs up all’isolatissima church of Santa Maria in Siaris, set on a steep rock wall karst. Monrupino, located high on a hill, is an observation point on the karst plateau.
