The Egyptian Antiquities Ministry announced this weekend that Czech archaeologists uncovered the burial site of a previously unknown queen in Abu-Sir on Sunday, reports the Guardian.

Abu-Sir was used as an Old Kingdom cemetery for the ancient Egyptian capital of Memphis. It is located southwest of Cairo along with several pyramids dedicated to Fifth Dynasty pharaohs.

The queen, who had not been known before the find, was found in the funeral complex of Pharaoh Neferefre who ruled 4,500 years ago.

"This makes us believe that the queen was his wife," Miroslav Barta, who lead the Czech Institute of Egyptology mission, said in a statement.

The queen's name, Khentakawess, and her rank had been found inscribed on a wall in the tomb, according to Egyptian Antiquities Minister Mamdouh el-Damaty. She's known as Khentakawess III since two previous queens have been identified with the same name.

The queen's tomb dates from the middle of the Fifth Dynasty (2994-2345 BC), according to an official at the antiquities ministry.

"This discovery will help us shed light on certain unknown aspects of the Fifth Dynasty, which along with the Fourth Dynasty, witnessed the construction of the first pyramids," Damaty said.

Archaeologists also found 24 limestone and four copper utensils in the queen's tomb, the statement added.

Neferefre ("Re is his beauty") was the first son of Neferirkare and Queen Khentkaus II to become Pharaoh. Researchers believe he reigned a short time due to the unfinished state of his intended pyramid. The Turin King List shows only a single vertical stroke for Neferefre's reign, which signifies one year. It suggests he had a reign of about one or two years, which agrees with the archaeological evidence that he died between the ages of 20-23.

In addition to discovery of the queen's tomb this weekend, History.com reports that another team of archaeologists discovered a symbolic tomb built for Osiris, the Egyptian god of the afterlife and the underworld. Osiris' tomb was constructed during the 25th dynasty, around 700 B.C., according to the Egyptian Antiquities Ministry.

In January 2014, archeologists in Egypt unearthed the burial site of a previously unknown pharaoh named King Senebkay who is thought to have ruled more than 3,600 years ago.
