Pignon is located at the border of the Central Plateau and North Departments. When France first acquired the western third of the island from Spain, Pignon laid right at the border of French and Spanish territories. It was founded in 1699 by Jean Guillaume de Pignon, one of the first French tradesmen and plantation owners who settled the western portion of Hispaniola after the Treaty of Ryswick with Spain. The vast valleys were suitable for tobacco, sugar cane, coffee, banana, mangoes, cocoa and animal production for export to France and trade with the Spanish neighbors in Hinche. The mountain chain overlooking the valleys provided protection against tropical storms and tornadoes, made the area even more desirable to Guillaume. Later, with over 700 male slaves in different plantations throughout the area, he and his family turned the area into a commercial trading hub of sort. He and his family settled the village, right at the foot of the mountain which bears his name to this day.
