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.

Hadrian's Wall is a former defensive fortification of the Roman province of Britannia, begun in AD 122 in the reign of the Emperor Hadrian. Running from Wallsend on the River Tyne in the east to Bowness-on-Solway in the west of what is now northern England, it was a stone wall with large ditches in front of it and behind it that crossed the whole width of the island. Soldiers were garrisoned along the line of the wall in large forts, smaller milecastles, and intervening turrets. In addition to the wall's defensive military role, its gates may have been customs posts.

Sections of Hadrian's Wall still remain, particularly in its hilly central sector. Little remains in lowland regions, where it was used as a source of stone for new buildings.
