Egyptian authorities promised Thursday they would move quickly to get new radar equipment needed to search for Queen Nefertiti’s tomb amid a new theory it could be in an alleged, hidden chamber behind King Tutankhamun’s tomb in the famed Valley of the Kings.

The theory, presented this summer by British Egyptologist Nicholas Reeves, speculates that King Tut, who died at the age of 19, may have been rushed into an outer chamber of what was originally Nefertiti’s tomb.

Archeologists have yet to find the tomb of Queen Nefertiti, fabled for her beauty and famous since her bust was discovered in 1912, now on display at the Neues Museum in Berlin.

Since the 1922 discovery of King Tut’s 3,300 year-old pharaonic mausoleum in the Valley of the Kings near the city of Luxor, his tomb has become the focus of attention for archaeologists world over — and one of Egypt’s prime tourist draws in modern times. Details
