Passing under the Porta Govese or Torresotto dei Piella you reach the famous window on the Canale delle Moline and the bridge, both overlooking the canal.  This corner of the city is known as "little Venice". Looking out among the buildings, you can see one of the few stretches of running water, which was not covered with asphalt between the beginning of the twentieth century and the postwar period.  Canale delle Moline is the extension of Canale di Reno. For the most part of its route the channel is locked between the houses and for this reason in the past it has long been hidden from view. Now it is possible to see it through small windows in via Oberdan, via Malcontenti in addition to via Piella.
