A history of the Antonine Wall and a guide to the surviving remains of Rome’s Northernmost Frontier

Westerwood to Bar Hill

Croy Hill

Access the Croy Hill footpath (turning left and keeping the electricity pylons on your left). You’ll almost immediately see a segment of ditch both in the field that sits between the public road you were previously on and to the right climbing the hill. The latter is particularly impressive and is well preserved as it was literally carved out of the rock - undoubtedly a backbreaking task! The path is sign-posted but is obvious - just follow the ditch.

Onwards from Dullatur

From Dullatur ditch, head under the railway bridge and follow the public footpath passing a number of farms. The path eventually intersects with the public road from Dullatur village. Throughout you are broadly following the path of the Wall.

This section of the Wall is almost exclusively accessed via a footpath that runs its entire length. Parking is available at Croy or Dullatur or further east at Castlecary.

Getting There

Westerwood Roman Fort

Westerwood Fort, whose Roman name is unknown, enclosed around 2 acres but there are no visible remains above ground. The Regiment that was stationed here is also unknown although an altar dedicated by the wife of a Centurion of the Sixth Legion (Legio VI Victrix) suggests a Legionary presence - a unusual scenario. The site is currently occupied by farm buildings.

This article details the line of the Antonine Wall from the site of Westerwood Roman Fort through towards the entry point for Bar Hill. It includes the stunning section of ditch at Dullatur and then climbs to Croy Hill. At the latter the rock cut ditch, impressive northern views and two so-called ‘expansions’ can also be seen. The vast bulk is a footpath with no vehicular access.

Croy Hill Fort and Fortlet

Croy Hill hosted first a small fortlet and then a larger fort. The former was around 22 metres by 18 metres and was sighted near the crest of the hill. Some historians suggest this was a fortification raised by Julius Agricola during his campaigns of the AD 80s where he established a Roman baseline across the Forth/Clyde isthmus. However this explanation has been discounted in recent times and it is more likely the fortlet was simply part of the initial configuration of the frontier when the bulk of garrisons were planned to be situated away from the line of the Wall itself with access provided by small fortlets such as this. This plan changed before the frontier had been completed with more troops moved onto the line of the Wall. The larger fort at Croy was constructed accordingly.

The fort enclosed an area a little under 2 acres and included the normal configuration for a Roman fort - a headquarters in the centre with granaries and barracks. A bath house was located outside the fort and, unlike at Bar Hill and Bearsden for example, was not contained within a defensive annexe enclosure. Unusually for an Antonine Wall outpost, but standard elsewhere in British Roman forts, a small civilian settlement was established to the immediate rear of the fort. Nothing remains visible of the fort itself but its location can be identified from the low stone walls of a later farmstead that occupied the site.

Note the portion of 'uncut' ditch. Did the basalt rock defeat even the Romans or was this left to facilitate access to the fort (but then why situate it offset to the east)? Some also argue it may have been the result of the convergence of two work crews.

Towards Dullatur

Continue west on the footpath noting that it does become a little boggy. The Golf course is on your right but you’ll soon come to a wooded area with steps taking you into an enclosed area which has an impressive section of ditch.

Dullatur Ditch

Towards Croy

Once you emerge on the public road its initial path mirrors the line of Wall. However, after a little over 50 metres, it bends sharply to the right whereas the Wall itself continued directly ahead into the (private) field. Keep following the road which skirts around the farm after which you can access the Croy Hill footpath.

Croy Hill Expansions

Keep following the ditch and as you reach the crest of the hill you’ll see Bar Hill, the site of the next Roman Fort on the Wall, in the distance. Nearby the confused earthworks to the rear of the Wall are examples of ‘expansions’. These were constructed in the same manner as the frontier itself with a stone base (in each case about 5 metres square) and earth rampart presumably built to the same height as the substantive Wall. They are generally accepted as signal platforms and the location here would make sense for it would enable Croy to contact Bar Hill and perhaps other signal stations to the north and/or south. Interestingly here at Croy the expansions were built after the Wall not concurrently (the stone base and turves of earth do not overlap). This may be linked with the upgrade from a fortlet to fort.

The footpath descends towards Croy village. Once you’ve descended down the slope you’ll see sign posts pointing you in the right direction. Take care crossing Howe Road and then head up the farm track.
