Archaeologists have unearthed more ancient ruins of what they believe was once a bustling port city near the capital of modern-day Morocco, digging out thermal baths and working-class neighbourhoods that the country hopes will lure tourists and scholars in the years ahead.

On Friday, researchers from Morocco’s National Institute of Archaeological Sciences and Heritage presented new discoveries made this year at Chellah, which is a 3.15-sq km UNESCO World Heritage Site with a footprint almost five times the size of Pompeii.
