San Giovanni Evangelista, Romanesque-style church in Turin, Italy

San Giovanni Evangelista is a church in Turin whose architect Edoardo Arborio Mella drew on 13th-century Lombard Romanesque style. It occupies a rectangle about 60 metres long and 22 wide, with a 45-metre bell tower on the facade. Inside, three naves are separated by six arches per side on pillars alternating 6 and 12 metres in height; the central arch rises 19 metres.

Don Bosco planned the church and its annexed institute because the San Luigi Oratory, founded in 1847, was not enough for the area. After buying land divided into small plots, he commissioned Count Edoardo Arborio Mella, who designed it in 13th-century Lombard Romanesque style. Archbishop Gastaldi blessed the cornerstone on 14 August 1878; the church was completed and consecrated on 28 October 1882, and Don Bosco celebrated the first Mass around noon.

Locals call it "San Giovannino" to tell it apart from the cathedral of San Giovanni Battista, Turin's patron. Don Bosco wanted it beside the Waldensian Temple on Corso Vittorio Emanuele II. The seven medallions on the side walls show the bishops of Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia and Laodicea named in the Apocalypse.

The church entrance is located on Corso Vittorio Emanuele II, making it easy to find. Visitors should note that the interior can be viewed during service hours when the doors are typically open.

The organ Don Bosco commissioned from Giuseppe Bernasconi of Varese was inaugurated in early July 1882 with morning and evening concerts, among them performances by Vincenzo Petrali of Bergamo; the press reported at least fifty thousand paying attendees. Its mechanical action was later converted to pneumatic by the Baldi firm in 1920 and to electric in 1935, so the Bernasconi instrument was never returned to its original form.
