Date for official opening still not announced for $1bn-plus mega-project more than a decade in the making

Egypt’s vast and much-delayed antiquities museum will partly open its main galleries on Wednesday, including 12 halls that exhibit aspects of ancient Egypt.

The Grand Egyptian Museum, a mega-project near the famed Giza pyramids that has cost considerably more than $1bn (£765m) so far, will open its halls to 4,000 visitors as a trial run until the official opening date, which is yet to be announced, according to Al-Tayeb Abbas, assistant to the minister of antiquities.
