Turret 58A (Newtown) was one of the small stone watch towers built at roughly third-mile intervals along Hadrian's Wall, positioned between Milecastle 58 (Newtown) and Milecastle 59 (Old Wall) in the central-western sector west of the River Irthing. Like its neighbours, it was constructed in the 120s AD under Hadrian and would have been a two-storey structure roughly 4–5 m square internally, manned by a small detachment drawn from the auxiliary garrison of a nearby fort, probably Castlesteads (Camboglanna). It was likely occupied intermittently through the 2nd and into the 3rd century, with most turrets in this sector abandoned and walled-up during later reorganisations of the frontier.

Its role was observation and signalling, providing line-of-sight communication between adjacent milecastles and turrets along this stretch of the Wall where it runs through gently rolling country south of the Solway plain. It is not individually notable, being one of around 80 such towers that together formed the integrated surveillance system of the frontier.
Very little is recorded for Turret 58A specifically; it has not been the subject of significant modern excavation, and the structure does not survive as an upstanding feature, having been ploughed out or robbed in the post-medieval landscape. Its position is known primarily from the regular spacing of Wall installations rather than from substantial in situ remains.

It is recorded in the Pleiades gazetteer of ancient places as a watch tower site from the Roman period in Britain.
