Entrance and the first few chambers were visited by James Burton in 1822, but the tomb was later buried by flood debris and backdirt from excavations nearby. It was not until 1995, when Theban Mapping Project (by Kent Weeks) relocated the tomb's entrance and explored its interior, that the tomb was found to be the largest ever found in the valley. So far, 150 chambers have been located, but the symmetrical plan of the tomb and the likelihood of more doorways if many walls mean that it is likely to contain at least 200 chambers.
