Bones found inside floor of 16th century Dutch building in red light district: report

Footbone’s connected to the floor boards.

Cow bones were discovered in the floor of a 16th century building in the red light district of Alkmaar in North Holland.

The floor, excavated by Heritage Alkmaar, is believed to date back to the 15th century and exemplifies a method of construction only rarely seen in certain parts of the European nation, according to a report from Fox News.

Craftsmen used the bones of cattle to fill in the place of tile in an ingenious way to repair busted surfaces.

“[The old floor is] not so remarkable, but what is remarkable is that the tiles are gone in some places and that those places are filled with a floor made of bones,” Heritage Alkmaar wrote in a post.

“This kind of floor is rarely found, and so far only in North Holland,” the post continued.

The building where the unique floor was found resides in Achterdam, which is the red light district of the Dutch city.

Bone-crafted floors have previously only been seen in the cities of Hoorn, Enkhuizen and Edam.

Remarkably, the height of the bones measures exactly the same as that of the floors, according to the archaeologists.

The bones were arranged in a pattern to seemingly fit as many as possible to create solid footing.
