Cripta Arqueològica de Sant Vicent Màrtir

Cripta Arqueològica de Sant Vicent Màrtir is an underground archaeological site in the historic core of Valencia, standing right next to the cathedral on Plaza del Arzobispo, opposite the City History Museum. In one compact space beneath the square, visitors can trace layers of the city's history running from Roman times through the Visigothic and Islamic periods into medieval Christian Valencia.

What is buried beneath the square?

Excavations uncovered a stretch of the Cardo Maximus, the main north-south street of Roman Valentia and a continuation of the Via Augusta within the city walls. A surviving fragment of Roman wall painting depicting the god Mercury points to the importance this part of the city held in antiquity.

In the 6th century, during the Visigothic period, a funerary chapel was built on the site, believed to have been intended to hold the remains of a bishop. The building formed part of a wider episcopal complex that also included the cathedral and neighbouring chapels — effectively the religious heart of Valencia at the time.

The site's next layer belongs to the Islamic period, when the space was repurposed as palatial baths, leaving a lasting mark on its layout and interior features. After the Christian conquest, around 1238, King Jaume I ordered a chapel built here dedicated to Saint Vincent Martyr — the memory of the saint's connection to this exact spot had survived through all the earlier transformations of the building.

What will you see inside?

The display combines the original architectural remains with objects recovered during excavation: the Roman wall painting, a Visigothic altar together with its liturgical screen, artefacts from the Islamic period, and a sculpture of Saint Vincent Martyr. Seeing them together makes it possible to follow how one small space was repeatedly claimed and reshaped by different civilisations over more than a thousand years.

How is the visit organised?

Visits are self-guided, and an audiovisual presentation explains the site's history in three languages — Spanish, Valencian and English. It's a useful introduction before walking through the archaeological remains themselves, which can otherwise be hard for a non-specialist to interpret unaided.

When is the best time to go?

Because the crypt sits right beside the cathedral, it's easy to combine a visit with a walk through the Barrio del Carmen or a stop at the neighbouring City History Museum. Given the site's small size and underground setting, it's worth timing your visit for a quieter moment, away from the busiest tour groups, so you can take in the exhibits and the audiovisual presentation without feeling rushed.

Frequently Asked Questions

Is the crypt located directly beneath Valencia Cathedral? Not directly underneath it, but immediately next to it on Plaza del Arzobispo — the site was part of the same historic episcopal complex as the cathedral.

What historical layers can you see here? Remains of a Roman street (the Cardo Maximus), a wall-painting fragment depicting Mercury, a Visigothic funerary chapel, traces of Islamic-era palatial baths, and elements of the medieval chapel of Saint Vincent Martyr.

Do you need a guide to visit? No — a trilingual audiovisual presentation guides visitors through the site's history, and the rest of the visit is self-paced.

How long does a visit take? Given the crypt's small size, a visit is fairly short — around fifteen to thirty minutes is enough to see the exhibits and watch the audiovisual presentation.
