Water taxis and ferry boats zip from central Venice to the islands, so you can easily see all three places in one day. A 13th century law restricted glass production (and its dangerous furnaces) to Murano to prevent fires on the main island, and also to protect the secrets of Venetian glassmaking. Shops proudly display these painstakingly produced works of art — made with only needles and thread by artisans meticulously following time-honored patterns passed down from older generations. Padua, half an hour from Venice by train, is home to a prestigious university, an important pilgrimage site and some remarkable frescoes. Giotto, considered the first modern painter, produced scenes that were more realistic and human than anything that had been done for a thousand years. Since the chapel is open only to a limited number of visitors a day, reservations are required. Padua also presents the opportunity to explore one of Italy’s finest produce markets. Because medieval times, shoppers have come to Palazzo della Ragione and its surrounding squares for the best Veneto produce. [...] you shouldn’t overlook the gems nearby, with their distinctive culture and history, sumptuous art and in-love-with-life people — embracing today with classic Italian flair.
