The grand Piazza Unità d'Italia, the largest sea-facing square in Europe, is the centre of the Habsburg-era waterfront, surrounded by the City Hall and the Palazzo del Governo. Nearby are the Roman theatre and the hilltop Cathedral of San Giusto and its castle. A little north, Miramare Castle, built for Archduke Maximilian of Austria, stands on a promontory in a park. Trieste's coffee culture is renowned, and the Caffè San Marco and other historic cafes serve coffee alongside pastries. Local food includes seafood, jota soup and buffet-style meals. A day is enough for the square, cathedral and Miramare, and the Barcola promenade is popular for summer swimming. Prices are in euros. The city is windy in winter when the bora blows, and can be crowded on summer weekends.
