Aosta's Enigmatic Underground Wonder: The Criptoportico Forense

Beneath the bustling Piazza Papa Giovanni XXIII in Aosta lies a captivating secret: the Criptoportico Forense, a remarkably preserved Roman structure that transports visitors back to the era of Augusta Praetoria. Dating back to the 1st century BC, this underground monument offers a unique glimpse into the architectural ingenuity and daily life of the Roman colony. The Criptoportico Forense is a horseshoe-shaped, semi-subterranean gallery that once surrounded the sacred area of the Roman forum. Measuring approximately 89 by 73 meters, the structure consists of two parallel corridors with barrel-vaulted ceilings, supported by sturdy travertine pillars. These pillars, meticulously plastered, create a sense of both strength and elegance. Lancet windows punctuate the walls, allowing soft light to filter into the depths of the cryptoporticus, adding to its mysterious ambiance. The precise purpose of the Criptoportico Forense remains a subject of scholarly debate. While it undoubtedly served a structural function, helping to level the uneven terrain and support the temples and colonnades above, its role may have extended beyond mere engineering. Some historians believe it functioned as a covered ambulatory for worshippers accessing the adjacent temples dedicated to the deified Augustus and the Capitoline Triad (Jupiter, Juno, and Minerva). Others suggest it may have served as a storage area for military supplies or other goods. Regardless of its exact purpose, the Criptoportico Forense offers a fascinating insight into Roman construction techniques and urban planning. The sheer scale of the structure, built with remarkable precision and attention to detail, speaks to the advanced engineering capabilities of the Roman Empire. The use of barrel vaults, a hallmark of Roman architecture, allowed for the creation of spacious and durable underground spaces. As you wander through the dimly lit corridors, imagine the bustling activity that once took place above. The forum was the heart of Roman Aosta, a vibrant center of commerce, politics, and religious life. The Criptoportico would have provided a sheltered space for people to gather, conduct business, or simply escape the elements. The Criptoportico Forense is conveniently located in the heart of Aosta, making it easily accessible to visitors.
