Actually, this is all down to a colleague.
She wondered if I knew about a “very famous” (her words) street market in Milan. She gave me the address but the piazza name she gave me didn’t exist.
She can be annoying at times.
So I went on the hunt for somewhere which listed the street markets in Milan.
Everyday there is a market somewhere.
Perhaps the most ‘famous’ is Papiniano. This is on a Saturday near the canals (Navigli) and stretches up a couple of long roads. It sells clothes, mainly. Not all street markets are the same. The one near me (on a Tuesday) sells mainly fruit and veg although there are at least a couple of stalls selling the usual street market stuff (clothes, household goods, etc.).
In fact, people looking for somewhere that’s the equivalent of Primark, here, would do quite well to go to the Papiniano market, since we don’t have either a Primark or, as far as I am aware, an equivalent.
But to get a full list of what street markets are where and when could look here. It’s a comprehensive list and shows a map for nearly all of the markets.
For certain, wherever you live there will be a market somewhere, nearby on one of the days in the week.
Update May 2015: It seems the link is currently broken. Here are some alternatives, although the link above was the best a it was easier to “see” the closest market to where you were living or staying.
1. Where the original map came from. Markets are listed by zone (but you need to know which zone you are in) but no other details (other than street name given).
2. Showing some of the “best” markets, ordered by day and linking to a map.
3. All markets and shown on a map. Click on each flag to bring up details of when it’s on. (In Italian, I’m afraid).
