The Bastione di San Maurizio (Bastion of San Maurizio_, characterized, like the nearby Bastion Verde, from the "casino" built at the summit and used as the interest of the Royal Palace's gardens, corresponds to the last platform of the defensive front that protected the area north eastern expansion of Torino (Turin).
As far as it is known, it seems possible to state that it was carried out between about 1670 and the following decade: the project elaborated by Sèbastien Le Preste de Vauban, asked about that date with regards to the breadth and depth to be assigned to the front facing towards the river Po. It still indicated in its place a bulwark of radically different form, while documented for the first time in the configuration preserved in a drawing by Michelangelo Morello. In fact, he already depicted a pentagonal bulwark, with straight sides without mumps, and with an angle of insertion in the curtain (of which today survives the stretch that connects the work with the Bastion Verde) completely consistent with what remains of the preserved arrangement in the Royal Gardens, without prejudice to the opening in 1912 of the passage to allow the tracing of today's Viale Primo Maggio.
