 In 1365 an historic peace was signed between the two factions at Pigna's Lago Pigo Bridge, next to Pigna's sulpha thermal springs, which became the dividing line between the territories of Provenza and the republic of Genoa.With the surrender of Nice in 1388 (a peacefully negotiated territory transfer, artfully managed by the Grimaldi's of Monaco) Pigna passed from Provence's control to that of Savoy, which reignited tensions with the neighboring village of Castel Vittorio (an ally of Genoa).At times, this conflict would take on the characteristics of rivalries between brawling children.
