Aesica (modern name Great Chesters) was a Roman fort, one and a half miles north of the small town of Haltwhistle in Northumberland, (not be confused with Chesters fort [Cilurnum]). It was the ninth fort on Hadrian's Wall, between Vercovicium (Housesteads) 6.0 miles to the east and Banna (Birdoswald) 6.5 miles to the west.
Its main purpose was to guard the Caw Gap where the Haltwhistle Burn crosses the Wall.[1]
