The first royal tomb discovered in over a century is shedding new light on the pharaoh who ruled before Hatshepsut.

An Egyptian-British team has found the tomb of an ancient pharaoh near the Valley of the Kings. This discovery marks the first pharaoh’s tomb found since 1922, when King Tutankhamun’s tomb was uncovered, reported The Washington Post. The tomb belongs to King Thutmose II, who ruled nearly 3,500 years ago.

A long lost tomb of an Egyptian pharaoh has been found, the country’s antiquities ministry said Tuesday, answering a great mystery of one of ancient Egypt’s most prosperous eras.
