Treviso, Italy: an underrated gateway to Venice The city once belonged to Venice, and it shows. The colonnaded Buranelli district was built for fishermen from Burano. Nearby, nudging the elegant palazzi, the covered fish market occupies its own little island, floating like a ship, filling the morning air with seafood aromas and pandemonium. As for art, you can find it all over town on frescoed house façades, their once brilliant colours faded to a chalky softness. There's an Annunciation by Titian in the seven-domed cathedral (and a portrait attributed to him in the town museum). Treviso is proud of its links with Giotto's follower Tommaso da Modena, and the Santa Caterina museum devotes a vaulted hall to his fresco cycle of the life of St Ursula. But for a taste of Tommaso's humanity and humour, step into the modest Dominican chapter house of San Nicolò and look up at the frieze running round the walls - 40 portraits of Dominicans at their desks. One friar looks questioningly over his spectacles; his neighbour has his nose in a manuscript; another blows on a just-sharpened pencil. All appear vibrantly alive . In the nearby church of San Francesco, Petrarch's daughter and Dante's son sleep in their stone beds. There are more churches to be seen, as well as fine medieval buildings and canvases by Renaissance artists, but Treviso is about taking things easy, not frenzied culture-chasing. Enjoy a tranquil moment leaning on a balustrade, watching the ducks glide by. Hire a bike and bowl along the Restera, a grassy, tree-shaded riverside path where, on Sunday mornings in spring, the locals enjoy a passeggiata on wheels. Treviso also has a notable shrine to retail therapy: it's the birthplace of Luciano Benetton, founder of the worldwide empire. The family lives locally and Benetton's flagship store dominates a central piazza. But I "m more interested in a less-famous local product, a culinary gem: radicchio rosso di Treviso. Vineyards from Treviso to Valdobbiadene Only in this corner of the northern Veneto is this variety cultivated - not the tightly furled red globes found in Britain, but curly crimson and white bundles of rapier-slender leaves. Beyond the old city walls lie the radicchio fields . Lucio Torresan, whose family runs an organic farm, talked me through the production process: after harvest the plants are trimmed, bunched and transferred to freshwater tanks in darkened sheds. Only the hearts - snowy spines and ruby leaves gleaming like porcelain - are sent to market, to be enjoyed from November to spring. Delicious as the crunchiest of salad ingredients, it's even better grilled or roasted, in risotto or pasta . Pliny commended it as a cure for insomnia. Its subtle, slightly bitter flavour is addictive. Treviso's other claim to culinary fame is the local wine: prosecco, which in recent years has been granted DOCG status, preventing the name from being used for wines made outside the protected area. Running from Treviso to Valdobbiadene, the prosecco route is lined with vineyards. The winemakers are keen to attract visitors, and it's hard to resist calling in for a tasting. I found the smallest, quirkiest winery up a footpath marked "L'osteria senz'oste" (The inn without host). Here, in a modest farmhouse kitchen, visitors let themselves in to find a fridge stocked with prosecco, cold meats and cheese, and an "honour box" to pay what they feel appropriate for what they've consumed. So the next time you take the cheapo route to Venice, why not leave the shuttle bus for another day? Remind yourself of the courteous manners and true hospitality of Italy, too often obscured in the frenzy of mass tourism . A café table with a glass of prosecco under the arcades, the sound of a tiny millstream racing past, dinner that includes a dish with radicchio rosso... Venice can wait.
