Cryptoporticus

The Cryptoporticus is an underground structure beneath the Roman forum featuring two parallel barrel vaults supported by a central row of arches. This construction extends approximately 87 meters and created a level foundation for the sacred area of Augusta Praetoria, the Roman name for Aosta.

The underground structure was built in the late first century BC as an engineering solution to create a level platform for the sacred area. Its construction reflected Roman technical expertise and was part of the city's development as an important military and administrative center.

The galleries served as covered passages connecting different areas of the forum and were used during religious ceremonies and public gatherings. Their design allowed people to move through the space while protected from the elements during processions and important events.

The underground galleries require some physical preparation as the passages are narrow and lighting is limited throughout the structure. Wear comfortable shoes and bring a light jacket since the interior remains cool and temperatures stay relatively constant year-round.

The eastern section once housed an early Christian baptismal font, revealing how the ancient structure was repurposed for new religious practices. This adaptation shows how pagan spaces were transformed and continued to serve important community functions during the early Christian period.
