It has been reported that on July 22, the Pope visited the remote hillside sanctuary of Vallepietra in the Lazio region, drawing renewed attention to a sacred site nestled 1,337 meters high on Mount Autore. Art historian Maria Milvia Morciano points out that the sanctuary houses a rare 13th-century fresco of the Holy Trinity, featuring three identical divine figures seated on a single throne without distinguishing attributes.
The Rare 13th-Century Trinity Fresco at Vallepietra
According to art historian Maria Milvia Morciano, the central sanctuary holds a fresco measuring over two meters high and approximately 1.60 cm wide. Unlike standard Western iconography, this Romanesque-Byzantine artwork portrays the Father, Son, and Holy Spirit as equal human figures sharing one throne. Each figure wears identical clothing, holds a book in the left hand, and raises the right hand in an ancient oratorical blessing.
Did you know? The Vallepietra sanctuary is built directly into a natural cave on Mount Autore and remains completely closed during winter months due to heavy snow and freezing temperatures, with the sole exception of the Feast of the Epiphany on February 16.
Myths, Legends, and Architectural Setting
Local tradition attributes the sanctuary’s founding to various historical and folkloric events. According to popular legend, a peasant ploughing a mountaintop watched his oxen tumble toward a seeming abyss, only to find them kneeling unharmed before a miraculous apparition of the Holy Trinity in a grotto. Alternative accounts cited by researchers point to Eastern monks or Saint Dominic of Sora as the original founders.
Pilgrimage Traditions and Ex-Votos
According to historical records, the annual pilgrimage season runs from May through the end of September. Communities from Ciociaria, the Aniene Valley, and Abruzzo hike for hours through the night before the Holy Trinity feast days. Pilgrims carry banners, sing traditional hymns, and recite prayers along the mountain paths. The museum beneath the square now houses historical ex-voto offerings left by these travelers, documenting recoveries from illness, escapes from danger, and other answered prayers.
