This sprawling flea market has brought street merchants to the north of Porta Palazzo since 1857. It's both fascinating and overwhelming, but can turn up some splendid vintage finds for the persistent and sharp of eye. The pace settles down come mid-afternoon and there are plenty of artfully dishevelled cafes and bars at which to grab a coffee or spritz.

　　The Gran Balon, with more specialised antique and vintage dealers, happens on the second Sunday of the month, from 8am.
