In 1989, a previously unknown well was discovered in the course of subsoil investigations in the core area of Weißensee Castle. During the scientifically documented excavation of the 27-meter-deep shaft, which took several months, various lost or discarded remains from the last 700 years, mainly from the Renaissance and the High Middle Ages, came to light. The well was lined with ashlars to a depth of 24 meters and widened underneath in the gypsum rock without any lining. The oldest of these finds date from the 13th century. Parts of them are on display in this exhibition. The well can best be dated by the contents of the leather belt pouch, which also include bracteates (coins minted on one side) minted in Pegau near Leipzig between 1235 and 1250. Together with the other finds from the layers near the bottom of the well, it can be assumed that it was commissioned in the first half of the 13th century. A comparison with depictions of everyday objects in the illustrations of the „Große Heidelberger Liederhandschrift“ reveals surprising similarities with the finds from the Runneburg fountain. The items on display here in the Romanesque town hall are of the highest cultural-historical value, as they are among the very few material testimonies of their kind from the High Middle Ages.
