At the north end of Polmont Woods lies a section of Antonine Wall ditch and outer mound.
The line of the wall is accessible through the woods a short distance south of the car park and is somewhat obscured by trees. The ditch is relatively easy to trace as a hollow running north-west from the east end of the wood toward the Millhall Burn. Access is via Smiddy Brae, a quiet road off the B904 Polmont to Grangemouth Road. There is a small car park just to the east of Millhall Gardens. Three paths lead off from here; the middle one, between wooden fence post gives quickest access to the ditch.
