The two open sides of the tower, the west and south, show that it was guarded by a ditch at from 40 to 70 feet distance, and this may have been continued all round. The tower stands a few yards south of the highway which traverses this district from east to west, and represents the Roman Way from Greta Bridge by Brough, Appleby, and Brougham, with branches northwards to Alston and Carlisle. At Bowes, as at Brough and Brougham, the road was strengthened by a camp, and Bowes tower stands within the camp, near its western boundary, and to the south of its central line. The ditches of the camp may be traced to the north and west, and partly to the east, and its area is about 130 yards, by 140 yards: to the south the ground falls sharply towards the deep bed of the Greta, and is defended by terraces and scarps, in which, a little west of the centre, is an opening probably for communication with the river. The remains of a Roman bath have been laid open outside the south-east angle, and a fragment of lead pipe, no doubt feeding it, was dug up in the adjacent churchyard. To the west are the remains of four small barrows in Roundhill Close, and the defence of the camp is strengthened by two watercourses at a short distance on the east and west fronts. Besides this camp there is one at Greta Bridge, 6 miles to the east, and two others at 6 and 8 miles to the west, of which one known as Raycross is regarded as a British camp, adopted by the Romans. The cross, commemorated in the name, is said to have been set up in 1067 to mark the boundary then agreed upon between England and Scotland. The further camp is known as Maiden Castle. Bowes is held to be the Roman Lavatræ. The position is well chosen, having considerable local elevation. It is 928 feet above the sea, and commands extensive views, especially to the south and east.
