Croy Hill Roman Fortlet
Croy Hill Roman Fortlet
Only an outer ditch and a pair of beacon platforms survive of this Antonine Wall fort atop Croy Hill. The nature of the rocky terrain meant that the Romans were not able to dig a ditch as they normally would, but had to cut through solid rock to create a defensive barrier outside the Wall.
The fort is smal, measuring 270 ft x 243 feet, enclosing an area of 1.5 acres. The fort was joined to the wall on its northwest side, and was defended by three ditches on the southwest and two ditches on the southeast. Within the fort is a large well and a rectangular bath house lies just outside the northern corner.

Excavations at Croy Hill revealed that the 2nd century fort lies atop an earlier Roman camp, which has been linked - though with precious little evidence - to the 1st century campaigns of Agricola in Scotland.
