The Musée de l’Ancien-Évêché is a museum in Grenoble dedicated to the history and heritage of the Isère department. Inaugurated in 1998, it is located in the heart of the historic center of Grenoble, near the cathedral, inside the ancient bishop's palace, a building proclaimed a Historic Monument from which the museum takes its name. The site presents in the basement the archaeological finds of great importance of the early Christian baptistery of the fourth century, testimony of the religious history of the city and the territory. The museum itinerary chronologically traces the history of the territory from prehistoric times to the present day. After the section of prehistory, as regards the ancient period it is possible to observe evidence of the Gallo-Roman period, and various objects of the first century, such as a funerary stele bearing the mention of Cularo, the ancient name of Grenoble. Several reconstructive models by Cularo help to understand the positioning of the cathedral within the ramparts and the detailed representation of the latter. The medieval section houses the seals of the Viennese dolphins, the helmet of Vézeronce and the two panels of the altarpiece of the chapel of the castle of Bon Repos executed at the end of the fifteenth century and liturgical objects from the treasury of the cathedral, including the reliquary of the Holy Thorn of Grenoble. The modern period is depicted with portraits of bishops who occupied the palace as well as architectural models that reproduce the evolution over time of the episcopal group.
To make the museum particularly popular are the exhibition rooms for temporary exhibitions of various kinds, regularly organized every year, which make the place an important center of the cultural life of Grenoble.
