62 meters in length, 22 meters in width, and a height of about 16 meters. In the middle, there is a tower for the equipment, 22 meters in length with a rectangular footprint. These were the original dimensions of the "Magazzìno di sofisticazioni sali di Margherita di Savoia," a reinforced concrete structure that, in the mid-1930s, when it was built by Pier Luigi Nervi, represented an intriguing promise of the future in terms of construction techniques.

We are in the midst of Italy's economic modernization, during the years when the IRI (Institute for Industrial Reconstruction) was founded, public works were undertaken, land reclamation projects were initiated, and there was a push for autarky, leading to an intensification of domestic food production.

In this context, the great engineer and entrepreneur Pier Luigi Nervi lived and worked. 

Often referred to as "the wizard of reinforced concrete," Nervi, after years of construction experience, grasped the mechanical and construction potential of concrete and reinforced concrete. 

In Margherita di Savoia, he therefore experimented with some of the knowledge that, along with his works, would earn him a place in international architectural history. The warehouse is somewhat like an inverted boat. The salts were dropped to the ground through 12 parabolic arches. This descent from above allowed for the formation of pyramid-shaped piles that perfectly mimicked the concrete curvatures of the structure. This created a form-structure relationship that would become a distinctive element of his work over time.

Although the warehouse was in operation for only a few years, it is by no means one of the "cathedrals in the desert" that characterized other dirigiste interventions. Firstly, because it is located in the largest salt flat in Italy. And secondly, because the degree of advancement and durability of the structure was such that for its expansion and the interventions it underwent in the second half of the 1950s, the same construction techniques were employed.
