San Bernardo alle Terme is a Baroque style, Catholic abbatial church located on Via Torino 94 in the rione Castro Pretorio of Rome, Italy.

The church was built on the remains of a circular tower, which marked a corner in the southwestern perimeter wall of the Baths of Diocletian[1] (its pendant is today part of a hotel building, 225 meters southeast from San Bernardo alle Terme).

In 1598, under the patronage of Caterina Sforza di Santafiora, niece of Pope Julius III, this church was built for the French Cistercian group, the Feuillants, under the leadership of Giovanni Barreiro, abbot of Toulouse.

[4] Later, after the dissolution of the Feuillants during the French Revolution, the edifice and the annexed monastery were ceded to the Congregation of St. Bernard of Clairvaux, after whom the church is named.

Devoid of windows, it receives natural light only from the large circular hole (impluvium) placed in the center of the octagonal dome.
