Egypt inaugurated the long-delayed Grand Egyptian Museum on Saturday, the world’s largest museum dedicated to its ancient civilisation — a megaproject also aimed at boosting the country’s tourism and troubled economy. Two decades in the making and located near the Giza Pyramids on the edge of Cairo, the museum showcases over 50,000 artefacts detailing life in ancient Egypt.

World leaders attended the grand opening ceremony in Cairo who touted the museum as “an exceptional event in the history of human culture and civilisation.”
