The late 16th century church of San Bernardo alle Terme was built into the remains of an ancient circular building that originally formed part of the Baths of Diocletian. The church is dedicated to St Bernard of Clairvaux (1090-1153).
The structure of San Bernardo is similar to that of the Pantheon (albeit on a smaller scale), a cylinder (22 metres in diameter) capped with a cofferred dome and an oculus. The interior is, perhaps, dominated by the eight large stucco statues of saints, the work of the sculptor Camillo Mariani (1567-1611), who completed them circa 1600. Beginning at the right, the saints are: St Augustine, St Monica, St Mary Magdalene, St Francis of Assisi, St Bernard, St Catherine of Alexandria, St Catherine of Siena and St Jerome.
The German painter Johann Friedrich Overbeck (1789-1869), founder of the group of artists known as the Nazarenes, is buried in San Bernardo alle Terme. Overbeck moved to Rome in 1810 and lived there for the rest of his long life. His funerary monument is by Karl Hoffmann.
