length) within the tomb indicate that the tomb was not completed by the time of Ramesses' death, with the completed hall of pillars serving as the burial chamber. Another notable tomb from this dynasty is KV19, the tomb of Mentuherkhepshef (son of Ramesses IX). This small tomb is simply a converted, unfinished corridor, but the decoration is extensive. The tomb has been newly restored and opened for visitors. Twenty-first Dynasty and the decline of the necropolis By the end of the New Kingdom, Egypt had entered a long period of political and economic decline. The priests at Thebes grew more powerful, and they effectively administered Upper Egypt, while kings ruling from Tanis controlled Lower Egypt. Some attempt at using the open tombs was made at the start of the Twenty-first Dynasty, with the High Priest of Amun, Pinedjem I, adding his cartouche to KV4. The Valley began to be heavily plundered, so during the Twenty-first Dynasty the priests of Amun opened most of the tombs and moved the mummies into three tombs in order to better protect them. They removed most of the treasure in order to further protect the bodies from robbers. Most of these were later moved to a single cache near Deir el-Bahari (known as TT320). Located in the cliffs overlooking Hatshepsut's famous temple, this mass reburial contained a large number of royal mummies. They were found in a great state of disorder, many placed in other's coffins, and several are still unidentified. Other mummies were moved to the tomb of Amenhotep II, where over a dozen mummies, many of them royal, were later relocated. During the later Third Intermediate Period and later periods, intrusive burials were introduced into many of the open tombs. In Coptic times, some of the tombs were used as churches, stables, and even houses. Minor tombs in the Valley of the Kings The majority of the 65 numbered tombs in the Valley of the Kings can be considered as minor tombs, either because at present they have yielded little information or because the results of their investigations were only poorly recorded by their explorers. Some have received very little attention or were only cursorily noted. Most of these tombs are small, often consisting of only a single burial chamber accessed by a shaft or staircase with a corridor or a series of corridors leading to the chamber. Nonetheless, some are larger, multiple-chambered
