Description
The site of Milecastle 38 is in the vicinity of Hotbank Farm, Little remains of the milecastle except rubble walls outlined by robber trenches.

Excavations
The milecastle was excavated in 1935 and found to be 18 m east–west by 15 m north–south. It was found to have a short axis, with a Type I gateway. Pottery finds indicated an occupation of the 4th century. There was a rectangular building in the south-west corner and a causeway, 3.6 m wide, to the east. A tombstone was found, inscribed "...us.. xit annis... mensibus du...ebus quinque", re-used as a pivot stone in the south gateway.

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 38 are known as Turret 38A and Turret 38B.
