Archaeologists are "excavating" a Roman city the size of Pompeii in the West Midlands without turning a spade or disturbing a single brick. With a range of experimental remote-sensing techniques, they are delving under the rolling countryside of Shropshire and piecing together a detailed matrix of the streets and buildings of Wroxeter.
Not only can researchers now tell what Viroconium Cornoviorum looked like when it finally subsided under the soil in the Dark Ages, but through the new process of "time slicing", an underground application of radar, they are able to chart the city's rise and fall during its 400 year history by sampling buried remains at a range of different depths.
