Mysteries in the Cathedral Treasury
The exhibition features about 40 of these finds that seem “out of place” at first glance and explains the scientific approach used to classify them. A prime example is the porcelain dragon: its origin remains a mystery—and that is precisely what makes it a symbol of the unexpected that can be found in historical collections.
