Nearly 200 years ago, human blood is said to have been incorporated into a ceremonial tomb built within a royal palace complex in what is now Benin, according to legend. Now, an investigation into the proteins found within the tomb's walls reveals evidence that the legend is true.
According to a new study, the tomb at Abomey, once the capital of the West African kingdom of Dahomey, contains proteins that could have come only from human blood, confirming the site's grisly history.
