With heavy emphasis on linens and old books, this is a great place to find gifts you can actually fit into your suitcase. Make sure you pop into the 13th-century church of Santa Croce, an artistic treasure trove that serves as a backdrop for the market. This is a great opportunity to seek out Campo San Maurizio, a picturesque square not far from St. Mark's. On December 16-18, collectors from the entire northeastern corner of Italy gather to sell small objects and paintings. Prices can soar, but it may be the only chance you'll ever get to hold an authentic 16th-century ornament in your hand.
Small items abound, including old maps and coins.
When your shopping is done, visit the local Picture Gallery to see Titian's portrait of St. Francis and many other lovely paintings.
