On your path from Cannaregio district towards Castello district, heading to the San Giovanni e Paolo square, you will certainly get into Campo Santa Maria dei Miracoli. I like this charming small square, surrounded by typical Venetian buildings and a tiny piece of canal, which is also a Gondola stop, making it easy to imagine this spot as a very beautiful classical painting!
Sometimes I stop by, sit on one of the benches, enjoying the lovely sight offered by the magnificent back of the Santa Maria dei Miracoli church. This church is one of my favourite ones in Venice, and from Campo Santa Maria Nova you can see its back, on the other side of the canal, and it is so beautiful you will just want to go there, turn around the corner and discover the rest of this marble masterpiece. In this square there is (of course!) a traditional Venetian bar (bacaro) where you can grab a glass of wine or a cicchetto, and a very old library with second hand books, comics, vintage posters and postcards. It is hard for a passer-by not to stop and breathe in such a magical atmosphere.
