On the last Sunday of every month, the banks of Naviglio Grande - the oldest canal in Milan - are transformed into a huge outdoor flea market. Bargain hunters and vintage lovers from all over the city flock to explore the 400 stalls that stretch for almost 2km along the waters edge. Here you can find everything from antique furniture to books, paintings, jewellery, second-hand clothes and vintage vinyl, glassware and porcelain. On sunny days, the market attracts a fascinating cast of characters, both young and old. Take a break from browsing the wares on offer and indulge in a spot of people watching. Better still, why not stop off for an ice-cream in one of the trendy cafès that line the canal?
