getting there: from Via Giulia turn left onto Via del Mascherone
Santi Giovanni e Petronio dei Bolognesi is a small church from the 16th century. It is situated in the ivy-covered street on Via del Mascherone that leads from Via Giulia and down towards Piazza Farnese.
The church was built in 1581 and belonged to the confraternity of Bologna. Most of the artists whose work was commissioned for the church were also citizens of Bologna who were working in Rome.
The copy of Domenichino's altarpiece in the sacristy is by an unknown artist.
