Close to Concordia Sagittaria there is to discover the lovely city of Portogruaro. It is less known to tourists, therefore you can have a good time there enjoing the city that kept its face for centuries.
There are many renaissance palazzos in venecian gothic style and a exceptional city hall that was build in 1300. Enjoy the flair having a walk through the city centre (which is not too big) visiting the antique mills.
You have been warned: it's not too difficult to fell in love to its beauty. At least You would not happen to be the first one.
