Egypt's Antiquities Ministry said archeologists have uncovered at least 20 ancient wooden coffins in the southern city of Luxor.
A brief statement from the ministry said Tuesday archeologists found the coffins in the Asasif Necropolis.
The necropolis, located in the ancient town of West Thebes, includes tombs dating back to the Middle, New Kingdom and the Late Periods (1994 BC to 332 BC).
Photos from the ministry show colored coffins with inscriptions and paintings. The ministry described it as one of the "biggest and most important" discoveries in recent years.
The ministry revealed it will release further details at a news conference on Saturday.
