Every third Sunday of the month, a flea market is held in the Old Town, which is known, among other things, for its selection of antique books. The flea market takes place on Piazza della Borsa, Via Torbandena, Via del Teatro Romano, and on Piazza dell'Unità d'Italia, right in front of Trieste City Hall. By the way, the flea market runs year-round and starts at 8:00 a.m. on Piazza della Borsa.
So you can't really miss the market.
Here you'll find an overview of other flea and weekly markets.
