The most notable of the collection of art objects are:
The Reliquary-phylactery of the tooth of Saint-Nicolas (13th century).
The angels of Humbert and the angels of Saudemont date from 1260 to 1270 with a height of 1.30m, gold-plated matte and gloss for those Saudemont. These are fine examples of the quality of medieval sculpture in northern France. They are classified as historical monuments since 29 November 1958. The originals are in the museum, while copies are contained in one of the chapels of Saudemont and the Humbert church.
