Established in 1482, this weigh house in Oudewater (near Utrecht) was originally meant for weighing (trading) goods. As witch trials became common in the 16th century, weigh house scales were also used for witch processes. Witches were believed to be light enough to float on water, so if a person was a witch or not could be easily proven by putting them on the scale. Unfortunately, most weigh house scales were manipulated, and many a person was condemned based on a rigged test.
In 1545, Emperor Charles V proclaimed Oudewater’s weigh house as the only fair weighing site in Europe – consequently, not a single witch was ever convicted here.
