The Naviglio Grande is a canal in Lombardy, Italy, connecting the Ticino river to Milan. It's like a water highway that was built way back in the day for trade and stuff. People used it to transport all sorts of things like salt, wine, and even manure! But now it's mostly used for irrigation. Some folks are trying to bring back boat traffic on the canal, which would be pretty cool. So yeah, it's a historic waterway with a lot of stories to tell.
