The unearthed tomb was found to the south of Cairo in an Old Kingdom necropolis Abu Sir. The complex includes a number of pyramids built for the Fifth Dynasty pharaohs, CeskeNoviny.cz says.
The tomb’s location and the inscriptions on the tomb’s walls helped the discoverer, Miroslav Barta, suggest that the queen was pharaoh Neferefre’s wife.
Antiquities Minister Mamdouh el-Damaty identified her as Khentakawess III in succession of two other queens with the same name.
"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," he commented as quoted by AFP.
The pharaoh and his wife ruled some 4,500 years ago, CeskeNoviny.cz conveys.
The archeologists also found 30 tools, The Express Tribune adds.
