Built between 1754 and 1766 by Matteo Pirona, the Grand Canal was one of the key elements of the new urban plan that led to the construction of the Borgo Teresiano. In the area now occupied by the Borgo Teresiano (from Corso Italia to Piazza della Libertà) there were once the salt pans. The area has been completely reclaimed, but the canals perpendicular to the quay were the subject of extensive studies. In fact, it was thought to excavate them more to expand the navigable surface of the city and facilitate the loading/unloading of goods directly from the warehouses erected on the banks, but the project was then abandoned and the Grand Canal remained the only canal in the city.
