WASHINGTON (Reuters) - In a glimpse into the future of archeology, researchers have used ground-penetrating radar to map an entire ancient Roman city, detecting remarkable details of buildings still deep underground including a temple and a unique public monument.

The technology was used at Falerii Novi, a walled city spanning 75 acres (30.5 hectares) about 30 miles (50 km) north of Rome, researchers said on Monday.
