Maiden Way: SSE (4) to Birdoswald (Birdoswald, Cumbria)
This signal station on the Maiden Way Roman road was excavated by Francis Haverfield who recognised and reported its Roman origins in 1901. It stands on Gillalees Beacon within line-of-sight of the Hadrianic Wall fort at Birdoswald, which lies about 4 miles (6.5 km) to SSE, and the signal station on Barron's Pike, about 2¼ miles (3.75 km) to NNE, both stations being associated with - and probably garrisoned from - the so-called "Northern Outpost" fort at Bewcastle, which lay out of sight about 2 miles (3.2 km) to NNW of the Butts.
The excavations conducted by Haverfield exposed the foundations of a stone-built tower, about 20 ft. (c.6 m) square at its base, with walls about 3¼ ft. (1 m) thick, still surviving to a height of about 5¾ ft. (1.75 m). Only a slight trace of the surrounding ditch system was recorded.
