KV12
Located in the Valley of the Kings, Tomb KV12 is an unusual tomb, used originally in the Eighteenth Dynasty of Ancient Egypt, and then again in the Nineteenth and Twentieth Dynasties. It was probably used for multiple burials of royal family members, similarly to KV5.
The builders of KV9 broke unintentionally into KV12 whilst excavating that tomb. James Burton, who visited the tomb in the 1820s or 1830s, recorded the presence of mummified remains.
