Besides locks and keys, the museum features an extensive collection of antique chests and coffers.

Visitors can admire the techniques of artisans from past generations in each of these handcrafted items which range from early Roman bronze and ivory coffers to Gothic prayerbook holders and the early Baroque Michel and Conrad Mann coffers.

Other items of special interest are etched iron chests from the Renaissance, several Boulle coffers and the famous Limoges Reliquaries from the Middle Ages.
