Discover more about Criptoportico Forense

Beneath the bustling Piazza Papa Giovanni XXIII in Aosta lies the Criptoportico Forense, a captivating and enigmatic monument that transports visitors back to the Roman era. This remarkably preserved subterranean structure, dating back to the 1st century BC, offers a unique glimpse into the architectural prowess and daily life of the ancient Romans. The Criptoportico Forense was an integral part of Augusta Praetoria, the Roman colony founded by Emperor Augustus in 25 BC. Situated beneath the sacred area of the forum, it served as a monumental backdrop to the temples dedicated to the deified Augustus and the Capitoline Triad (Jupiter, Juno, and Minerva). While its precise function remains a subject of scholarly debate, it is believed to have served multiple purposes, including providing a covered walkway for religious processions, a storage area for military supplies, or a space for commercial activities. The structure itself is an architectural marvel, consisting of a U-shaped gallery that extends for approximately 89 meters on its longest side and 73 meters on its shorter sides. The galleries are divided into two naves by a series of arches, with barrel vaults supported by sturdy travertine pillars. Lancet windows provide natural light and ventilation, creating an atmospheric and evocative space. The consistent temperature inside the Criptoportico, regardless of the season, adds to its allure. For centuries, the Criptoportico's true purpose was shrouded in mystery. Some theories suggested it served as a military warehouse or granary, while others proposed it was a place of religious significance. Recent studies, however, have largely dismissed the warehouse theory, emphasizing its structural role in leveling the ground and supporting the temples above. During the medieval period, the Criptoportico was repurposed as a cellar, known locally as the "Marché des Romains." Today, the Criptoportico Forense stands as one of the few accessible forensic cryptoporticos in Europe, offering visitors a tangible connection to Roman history and culture. As you descend into the dimly lit galleries, you'll be transported to a world of ancient rituals, bustling commerce, and architectural grandeur.
