The Musée archéologique Saint-Laurent is an archaeological museum in Grenoble. It is located at the foot of the Bastille hill, one of the oldest points in the city. In fact, the museum is housed in the ancient Saint-Laurent church, a church built on the remains of a Gallo-Roman necropolis. Deconsecrated in 1983, the church now houses the museum collection. The site testifies to the span of time that goes from the formation of the fourth century necropolis to the present day, passing through four major phases in particular: the one that goes from antiquity to the beginning of the Middle Ages, marked by funerary traditions and the Christianization of the place; that of the construction of the 11th century Carolingian church, in which it is possible to see a decline in funerary cults in favor of a greater practice of Eucharistic offices; the monastic period, starting from the 11th century, which saw the presence of the Benedictines of Saint Chaffre until the end of the priory in the 18th century; finally, the last phase is that starting from the nineteenth century, with the awareness of the historical and archaeological interest of the site and the beginning of its restorations. Inside the archaeological site it is possible to visit the Saint-Oyand crypt, datable to the 6th-7th century, in which there are prestigious decorations of medieval sculptures and reliefs.
