(CNN)Archaeologists unearthed two 500-year-old skeletons of a woman and child underneath the Tower of London's chapel, the curator of the Historic Royal Palaces announced.

The Chapel Royal of St. Peter ad Vincula is known as the burial place for famous Tower prisoners, including three queens of England: Anne Boleyn, Catherine Howard and Jane Grey. All were executed in the 16th century, and their headless bodies were buried under the chapel without a memorial, the organization's website says.
