The church of San Macuto is a church on Piazza di San Macuto in the Colonna rione of Rome, Italy. Located next to the Jesuit Collegio di San Roberto Bellarmino in the Palazzo Gabrielli-Borromeo, it is the only church in Italy dedicated to the Breton saint Malo.
First recorded in 1192, the church of San Macuto has had several owners at different times. In the second half of the 13th century it was dependent on San Marcello al Corso, then later it belonged to the Dominicans from the neighbouring Santa Maria sopra Minerva (confirmed by Niccolo III in 1279). In the year 1422 it was described as a parish church. Pope Leo X joined the parish with that of St. Peter's Basilica in 1516, giving it to the Fraternity of Bergamo in 1539.
The Bergamo monks changed the saint it was dedicated to from Bartholemew to Alexander of Bergamo and the church got a new façade around 1560. The façade was a project of the Ferraran architect Giovanni Alberto Galvani and it was partially reconstructed 1577−1585 to the design of Francesco da Volterra.
Following a decision by Pope Benedict XIII, the Bergamo monks bequeathed their church to the Jesuits from the neighbouring palazzo in 1725−1726. They moved to a church then called Santa Maria della Pietà instead, and changed its name to Santi Bartolomeo ed Alessandro dei Bergamaschi (on the Piazza Colonna). The Jesuits rededicated the church to Saint Malo, following the vicissitudes of history together with the adjacent palazzo (later called Palazzo Gabrielli-Borromeo), which had longer been known as belonging to the Jesuits. It served as the church for the Pontifical Roman Seminary, the Board of Ecclesiastical Nobles, the Collegium Germanicum et Hungaricum and the Pontifical Gregorian University (1873−1930). Since 1942 it has been part of the Collegio Bellarmino, formerly belonging to the Roman Province of Jesuits, now an international home for the religious order.
