Mestre has several sights in the main Piazza, Piazza Ferretto. There is a watchtower at the top of the piazza, and be sure to check out Teatro Toniolo, which is a beautiful theater. Piazza Ferretto is a typically Italian Piazza, with a modern water feature at the center and lots of different eateries with outside seating. It is also full of top end designer stores. There are two local parks in Mestre which are worth visiting. The first is Parco San Giulliano, which is often used for outdoor concerts in the summer. Parco San Giulliano has a remarkable and unique view of Venice lagoon as it borders the Ponte della Liberta', what joins the Venetian islands with the mainland. Parco Bissuola is another local park, offering good sport facilities and an outdoor pool. Mestre is a very charming city, with its canal snaking across the center. There are plenty of gorgeous little streets to explore along the way.
