At a small, little-known jewel of Roman Baroque architecture Edilerica professionally managed an “emergency” intervention aimed at averting accidents. The gradual detachment of plaster from the chapel’s exterior walls and the now unbearable humidity in the building necessitated a sudden and radical intervention. Through the complete removal of the flooring and the rebuilding of the waterproofing structures underneath, the use of breathable materials in the redoing of the plasterwork, and the design of a dehumidification system for the rooms located under the chapel, it was possible to give new life to this delightful structure, located in the small circular church of St. Bernard at the Baths and nicknamed by many as the “little Pantheon.”
