Rare Bone-Filled Floor Discovered in Alkmaar

During renovations in Alkmaar, Netherlands, archaeologists uncovered a rare floor partially made of cattle bones, specifically metacarpals and metatarsals, replacing missing tiles from an old tiled floor. This unusual flooring technique, primarily found in North Holland, is believed to date back to the 15th century, although the current building, which stands on Achterdam Street, was constructed in 1609. The bones were meticulously cut to the same height and arranged in a specific pattern, with some placed with their tops facing up, suggesting a deliberate intention behind their use. Experts are puzzled by the choice of using bones instead of tiles, speculating it could be a cost-effective solution or linked to local trades. As excavations continue, archaeologists hope to determine more about the dimensions and purpose of this ancient flooring. Nancy de Jong, an archaeologist involved in the project, emphasized the privilege of uncovering such historical elements that contribute to the narrative of Alkmaar's past.
