In the heart of Alkmaar, a city steeped in history, archaeologists have made a remarkable discovery—a floor constructed entirely of meticulously arranged cattle bones. Hidden beneath layers of loam and tiles, this peculiar find in Achterdam, the city’s red-light district, has left experts and history enthusiasts intrigued. Dating back to as early as the 15th century, this unique bone floor offers a fascinating glimpse into the region’s past, revealing stories of resourcefulness, craftsmanship, and cultural evolution.
Unveiling the Bone Floor
Archaeologists stumbled upon the bone floor during an excavation in Achterdam, a district best known today for its vibrant red-light history. Beneath layers of soil and a more recent tiled floor, they uncovered rows of cattle metacarpals and metatarsals, each cut to the same height and carefully arranged. This discovery, unlike anything typically found during such digs, adds a curious chapter to the story of Alkmaar’s architectural evolution.
Though the building itself was constructed in 1609, experts believe the foundation and the bone floor date back much earlier, possibly to the 15th century. This hypothesis is supported by the style of the bones and their placement, which aligns with practices of the time. Nancy de Jong, an archaeologist for the municipality, explained that older foundations often underlie newer buildings, reflecting how Alkmaar evolved over centuries.
The bones used in this peculiar floor were identified as metacarpals and metatarsals from cattle. All were cut to a uniform height and arranged with precision. Experts speculate that their placement may have served practical purposes or held symbolic meaning, adding layers of mystery to the discovery.

Historical Context of Bone Floors in North Holland
While unusual, bone floors are not entirely unprecedented in the Netherlands. Similar discoveries have been documented in nearby cities such as Hoorn, Enkhuizen, and Edam. In these cases, bones were often combined with tiles, suggesting this was a deliberate and perhaps regionally specific building technique.
The exact reasons behind using bones as flooring remain speculative. Economically, bones may have been a cost-effective alternative to tiles. This would have been especially practical in areas where cattle farming was prevalent, and bones were abundant. Alternatively, the arrangement of bones might reflect a unique craftsmanship practice, perhaps tied to a trade or symbolic tradition.
Beyond practicality, the use of bones might carry cultural significance. As Alkmaar evolved, the district’s craftsman roots may have influenced such resourceful building practices. The bone floor could also reflect the ingenuity of local builders who repurposed materials in creative ways.
The Archaeological Process
Uncovering the bone floor was a meticulous process. Layers of loam—a mixture of sand, silt, and clay—covered the bones, which were then overlaid by a modern tiled floor. The team carefully removed these layers to expose the ancient foundation, ensuring that the fragile bones were preserved for further study.
The discovery is not just an anomaly; it provides rare insight into building practices and daily life in the 15th century. The bone floor adds a tangible element to Alkmaar’s history, bridging the gap between its medieval past and the present.
Exploring Achterdam’s Historical Evolution
Achterdam has undergone significant transformation over centuries. Originally a hub for traditional crafts like barrel making and hat making, it later became Alkmaar’s infamous red-light district. The bone floor, likely laid during the craftsman era, stands as a testament to this earlier phase of the district’s history.
During the Middle Ages, Alkmaar was shaped by the Christian church’s influence. While the church deemed certain trades and practices, such as sex work, objectionable, it also acknowledged their necessity in society. This duality underscores the district’s evolution from a craftsman’s quarter to a regulated red-light area.
Today, Achterdam is the only street in Alkmaar where window prostitution is permitted, following strict municipal regulations. This modern identity contrasts sharply with its historic roots, yet the discovery of the bone floor bridges these eras, reminding us of the district’s layered history.
Implications of the Discovery
The bone floor opens up new avenues for research. Experts plan to analyze the bones further to determine their exact age, origins, and potential uses. Such studies could reveal whether the floor had a purely practical purpose or held deeper symbolic meaning.
This discovery reinforces the unique building traditions of North Holland. By uncovering such rare artifacts, archaeologists gain a better understanding of how communities adapted their resources and navigated societal challenges.
Beyond its historical significance, the bone floor invites reflection on Alkmaar’s journey through time. It underscores the ingenuity of past generations while highlighting the city’s ability to preserve and celebrate its heritage.
Conclusion
The discovery of a bone floor in Achterdam is a fascinating reminder of Alkmaar’s rich and complex history. From its meticulous construction in the 15th century to its unearthing in the 21st, this unique artifact bridges centuries of evolution. As archaeologists delve deeper into its mysteries, the floor offers a rare glimpse into the lives and practices of those who came before, enriching our understanding of Alkmaar’s past and its enduring legacy.
