San Bernardo alle Terme is a basilica church in Rome, Italy.
The church was built in 1598 and was initially given to a French Cistercian group, the Feuillants, through the intercession of Caterina Sforza di Santafiora. Later, after Feuillants disgregation during the French Revolution, the edifice and the annexed monastery were ceded to the Congregation of St. Bernard of Clairvaux, to whom the church is entitled.
The German painter Johann Friedrich Overbeck, founder of the Nazarene art movement, is interred here. The most recent Cardinal Priest of the Titulus S. Bernardi ad Thermas was till his death Mar Varkey Vithayathil.
The structure of San Bernardo alle Terme is similar to the Pantheon, since it is cylindrical, with a dome and an oculus. The edifice has a diameter of 22 meters. The dome decoration, made of octagonal coffers, reminds one of the Basilica of Maxentius. The interior is graced by eight statues of saints, each housed in wall niches, the work (c. 1600) of Camillo Mariani. These are a good example of the so-called International Mannerism. The Chapel of St Francis is an addition to the ancient rotunda, and contains a sculpture of that saint by Giacomo Antonio Fancelli. The construction of the church recycled the remains of one of only two circular towers, which marked the corners the southwestern face of the perimeter wall around the Baths of Diocletian, the other tower is today part of a hotel building and lies 225 meters southeast from San Bernardo alle Terme. Between these two tower-like structures, also part of the same perimeter wall, there used to exist large semicircular recess, similar to an exedra and was probably used as an Sphaeristerium, Nowadays, the enormous scale of this recess and that of the wall itself may only be imagined from the layout of the modern Piazza della Repubblica, which followed the original layout of the ancient wall.
