ALGIERS, ALGERIA - An archaeological treasure trove on the site of a planned metro station in central Algiers is set to become a museum, opening a window on 2,000 years of history.

The site, close to the Algerian capital's UNESCO-listed casbah, has yielded remains from the city's Roman, Byzantine, Ottoman and French periods.

"It was spectacular," said archaeologist Kamel Stiti, co-director of the excavations. "In one look, you could see two millennia of Algiers' history."
