The antiquities ministry is to hold a press conference on Sunday afternoon to explain the extent of the damage caused to the Islamic Museum in Friday's bomb blast.
Antiquities Minister Mohamed Ibrahim said a short documentary and slide show would show the level of destruction caused to the exhibits and the building.
Ibrahim thanked UNESCO General Director Irina Bokova for offering $100,000 to help restore the museum.
Bokova also said a team of international experts would arrive in Egypt by the end of the week to inspect the museum and advise on its restoration.
The UNESCO grant is a great initiative and will encourage other international authorities to help, Ibrahim added.
The museum was severely damaged in a terrorist attack targeting the nearby police headquarters on Friday.
