Trieste is an interesting city and a flourishing center of trade and commerce. It was a literary and cultural center in the 20th century, and the town has Viennese influence and style – along with grand squares, palazzi and churches. The main square, Piazza dell’Unita d’Italia, has Viennese cafes, Palazzo del Governo, and Palazzo del Comune with its clock tower. All of these buildings were built in the 19th century. The promenade is a worth a stroll. Upper town, Colle di San Giusto – with its terrific views – has beautiful Castello di San Giusto and its musuem at the top of the hill, Piazza Cattedrale. Basilica di San Giusto is two churches in several styles, including Roman and Byzantine, with frescoes depicting San Giusto (the town’s patron saint), mosaics, and the lovely rose window. The civic museum here has art, religious items and historical items inside. Orto Lapidario displays pottery and statues. Visit Civico Museo Revoltella. Stop at Castello di Miramare and her gardens. Villa Opicina has a wonderful belvedere and views, and Grotta Gigante is an amazing walkable cave museum.
