A location at Tamfourhill, 1½ miles (2.5 km) west of the centre of Falkirk, Watling Lodge, includes a Victorian villa but is best known as the best preserved and most dramatic section of the Antonine Wall.
The villa was built in the 1890s on the site of a 2nd-century Roman fortlet, of which no trace survives. The villa is in the Arts and Crafts style and is now used by the Barnardo's charity as an outreach centre for young people suffering as a result of drug, alcohol or solvent abuse.
The fortlet provided a gateway through the Antonine Wall, which extends to the east and west, and here comprises a substantial ditch, around 12m (40 feet) wide and 4.5m (15 feet) deep. A short distance to the south of the ditch are the remains of the turf rampart, laid on a stone foundation. This rampart would once have supported a wooden walkway protected by a wooden palisade. This walkway would have had an uninterrupted view of the land to the north. The fortlet here was most-likely typical of those found elsewhere on the wall, with a 'friendly' entrance through a gate to the south and a northern gate giving access to the land beyond the frontier. There was a military road running along the rear of the Wall for its entire length.
