 At the end of the 18th century the new House of Lorraine’s Dukes gave a great impulse to the town economy.Thanks to the Ducal works for the reclamation of the territory and the opening of two new roads, that joined Pontassieve to the Casentino and Emilia, Pontassieve lived a remarkable economic growth.Under the Lorenese domination Pontassieve was elevated to the rank of Vicarship’s Town Hall comprising part of the territories belonging to the Arno and Sieve valleys.
