Inveravon is sited on the east side of the River Avon in Scotland. It was long considered to be the likely site for a Roman Fort on the Antonine Wall in Scotland. The fort is one of the most dubious on the wall although some excavation and geophysics has been done. Near Inveravon Tower, the bare traces of a fort were found but there is nothing that an unskilled visitor could identify. Several excavations have unearthed the site's foundations as well as a section of the Military Way. Cobbled surfaces and some stone walls were found. Also ‘expansions’ were discovered, perhaps used as signal or beacon towers.

The Antonine Wall was a turf fortification on stone foundations, built by the Romans across what is now the Central Belt of Scotland, between the Firth of Clyde and the Firth of Forth. Built some twenty years after Hadrian's Wall to the south, and intended to supersede it, while it was garrisoned it was the northernmost frontier barrier of the Roman Empire. It spanned approximately 63 kilometres and was about 3 metres high and 5 metres wide. Lidar scans have been carried out to establish the length of the wall and the Roman distance units used. Security was bolstered by a deep ditch on the northern side. It is thought that there was a wooden palisade on top of the turf. The barrier was the second of two "great walls" created by the Romans in Great Britain in the second century AD. Its ruins are less evident than those of the better-known and longer Hadrian's Wall to the south, primarily because the turf and wood wall has largely weathered away, unlike its stone-built southern predecessor.
