The town of Limite has ancient origins, but saw its major development after the 15th century, when its optimal position made it one of the places where the activity of boat builders could best be established, toward use for commercial purposes, especially for transport of goods and raw materials along the navigable stretch of the river, that is, the stretch downstream of La Gonfolina, on to the ports of the Tyrrhenian Sea. Limite sull’Arno overlooked one of the wide meanders of the Arno, which due to the particular, local absence of currents, tended to widen in that spot, producing an expense of water ideal for the construction of navigational hulls on the site. The raw material, wood, was supplied by inhabitants of the communities situated a little further upstream, like the castle of Castra and the villa of Conio, who had access to the woods of Montalbano. When Leonardo depicted this stretch of the Arno in his numerous papers, he rendered perfectly the shape of the meanders generated by the slow course of the river after La Gonfolina, between Limite and the Empolese plain (Madrid II, f. 22v-23r; Windsor Castle RL 12685 ). Leonardo’s drawings of the Arno Limitese, which date back to the early 16th century, are to be considered the last image of that particular river, which made possible the birth and development of the activity that, for the following centuries, characterized the hamlets of Limite and Castellina. Only a few decades later, in fact, during the second half of the century, the river was rectified through a major operation of reclamation, which radically changed its course, leaving on the ground, in front of Limite, the trace of the fossil meander, indicated by the toponym Arnovecchio. Today this area is a nature reserve making part of the Centro di Ricerca, Documentazione e Promozione del Padule di Fucecchio (nonprofit organization), where you can observe the flora and fauna typical of wetland marsh areas.
