Santi Ottavio e Compagni Martiri is a modern parish church at Via Casal del Marmo 110 in the suburb of Ottavia, just west of the train station.
The patron saints, Octavius, Solutor and Adventor, were martyred at Turin in the early 4th century. The parish is administered by the Congregation of St Michael the Archangel, familiarly known as the Michaelites.
The church was designed by Francesco Fornari, and completed in 1950 in a simplified neo-Romanesque style on a rectangular plan with a segmental apse attached. The entrance door has a horizontal floating canopy, and over this there is a round window with the fenestration forming a cross. Entrance and window are in a large arched recess in the gabled façade. There is no other decoration. The walls of the church are rendered in pale green.
