Cairo - A previously unknown pyramid estimated to be 4,300 years old was discovered in Egypt's desert, Egypt's Secretary General of Antiques Zahi Hawass said on Tuesday.
The pyramid, five metres high with a square base of 22 metres on each side, is believed to belong to Queen Seshseshet, mother of King Teti, the first king of ancient Egypt's Sixth Dynasty, Hawass said.
Teti came to power in 2323 BC.
The pyramid is the 118th discovered in Egypt and originally was 14 metres tall, Hawass said at a press conference.
