1732 - Horsley surveyed the milecastle, recording its position.
1776 - The location was visited by Stukeley, who sketched the area for his Iter Boreale'.
1789 - Brand visited the site, but noted that many of the stones had been removed from the foundations some years previously, for use in the building of an adjoining house.
1848 - Collingwood Briuce reported that a small, partly illegible altar had been found close to the presumed site of the milecastle. The altar (NMR Number: NZ 26 SE 227) was dedicated by Julius Maximus. Having searched the area, he could find no trace of Roman remains.
Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 3 are known as Turret 3A and Turret 3B.
