Raphael’s Vatican Loggias Enter a Five-Year Restoration Campaign
The Vatican Museums have begun an unusually large conservation effort on one of the Renaissance’s most elaborate fresco cycles. This week, more than 20 specialists started work on Raphael’s Loggias, the 65-meter sequence of painted bays in the Apostolic Palace that was created between 1517 and 1519 for Pope Leo X.
The project will unfold over five years and focuses on a work that has endured centuries of environmental stress. The Loggias occupy 13 bays on the second floor of the Apostolic Palace, overlooking a covered promenade, where scenes from the Old and New Testaments are set within a decorative program inspired by Roman ornament. According to the Vatican Museums, the restoration will address deterioration in the paint surface as well as the effects of the corridors’ microclimate.
One of the more striking complications is historical irony. Glass windows installed in the 19th century were meant to protect the frescoes from the elements, yet conservators now believe they helped create conditions that contributed to damage. For roughly 400 years before that intervention, the Loggias were exposed to rain, sunlight, snow, and humidity. Preliminary analysis has also identified two decorated sections on an angled wall that were inadvertently shielded from light, preserving their original chromatic intensity.
Angela Cerreta, deputy head restorer for paintings and wooden materials, said the team will first stabilize unstable paint before cleaning the frescoes with fiber lasers. Retouched areas will then be color-matched using techniques that keep new work legible without overwhelming the original surface. Work is currently concentrated on four bays before moving through the rest of the gallery.
The restoration is being supported by $5.5 million from the “Legacy of Raphael: The Vatican and Beyond” initiative, a World Monuments Fund project that includes restoration, training, and digital documentation. That initiative was funded by a $14.3 million donation from the Stephen A. Schwarzman Foundation, while the Patrons of the Arts in the Vatican Museums also contributed to the installation of the new windows.
The campaign places Raphael’s decorative vision back at the center of a long-running conservation challenge: how to preserve a fragile masterpiece without erasing the evidence of its history.
