Egyptian Prime Minister Mustafa Madbouly and other officials were on hand this week as the Djoser Pyramid was reopened following its restoration. The Saqqara necropolis, with its antiquities and tombs dating to the most ancient periods of Egyptian history, is an open-air museum. The necropolis also includes the Serpeum, where the Apis Bulls were buried. The Djoser Pyramid, located near the city of Memphis, is the oldest large-scale stone building in the world.
