The collections of the municipal museum are numerous. The centerpiece is undoubtedly the invaluable Carolingian Evangelical. The Evangelical contains the texts of the four gospels and is kept in a glass cage, protected from manipulation. It was digitized in 2007, to allow everyone to consult it on an interactive kiosk.
