In 1736 Carlo Emanuele III ordered the architect Felice De Vincenti, an Artillery Captain and later "Greater Teacher of Artillery", to build the Palace; he directed the works carried out by military personnel of the Royal Corps of Artillery.
The construction of the Palace lasted several times but in 1752 the Palace hosted the Arsenal and the Theoretical and Practical Royal Schools of Artillery and Fortification.
It is possible to individualize the typical lines of an arsenal: the grand basements, linked to the surface through wide ramps; the robust pillars to support weights; the wide rooms surmounted by dome-shaped vaults that represent the main architectural element of the Palace.
The current façade between Arsenale Street and Arcivescovado Streed, the main entrance of the Palace, was realized in 1890 by Captain Emilio Marrullier of the Engineer Corps who modified the original project of De Vincenti.
On the columns along the sides of the entrance there are two statues representing the Artillery and the Engineer Corps; above the gate, a plaque remembers the goals of the building: "Under the reign of Carlo Emanuele III, in Piedmont that raised militarily, this War Arsenal was designed by Felice De Vincenti as military defence, school, laboratory, and it was finished by Umberto I".
