Carrawburgh is a settlement in Northumberland. In Roman times, it was the site of a 3+1⁄2-acre (1.5 ha) auxiliary fort on Hadrian's Wall called Brocolitia, Procolita, or Brocolita.
The Vallum is a huge earthwork associated with Hadrian's Wall in England. Unique on any Roman frontier, it runs practically from coast to coast to the south of the wall. It was built a few years after the Wall.
