For the fictional city in the works of M. John Harrison, see Viriconium.Viroconium or Uriconium, formally Viroconium Cornoviorum, was a Roman town, one corner of which is now occupied by Wroxeter, a small village in Shropshire, England, about 5 miles (8.0 km) east-south-east of Shrewsbury. At its peak, Viroconium is estimated to have been the 4th-largest Roman settlement in Britain, a civitas with a population of more than 15,000. The settlement probably lasted until the end of the 7th century or the beginning of the 8th. Extensive remains can still be seen.
