[2] The early history of the castle of Valvasone tells how in 1218 CE the original manor-house was kept by Ulvino and Bonfante for the Patriarch of Aquileia.

When Walterpertoldo died, and the first generation of the Spilimbergo ended, a contest for the succession in controlling Valvasone began between two really important families in the area: the Zuccola and the Cucagna.

In that period Valvasone had a militar structure, but it was also the residence of those nobles who built the real village, the precursor of the modern town.

In the 1350s the nobles decided to enlarge the village: in this way they create one of the most beautiful examples of medieval town-planning in west Friuli.

For about a decade the look of the town remained basically the same, but after the fall of the Patriarch and the arrive of the Venetians, the structure of Valvasone wasn't adequate to sustain the increasing commerce and traffic along the way Portogruaro-Venzone.
