Hidden deep within the crypt of the Saint Catherine Church lies a true gem: the Treasury of Saint Catherine. Here, you will discover a remarkable collection of religious masterpieces, featuring Anglo-Saxon vestments, among the oldest in Europe; early medieval relics, and exquisite silverwork. Many of these treasures have been officially recognized as Flemish Masterpieces due to their exceptional historical, artistic, and scientific value.

The museum recieved a refreshing renovation in 2025. The Treasury reopened in a fully renewed setting, enriched with modern multimedia and interactive experiences!
