Kinneil’s Roman Fortlet is one of the milecastles built by the Romans around 140 AD as part of the Antonine Wall, the Empire’s most northerly frontier.

Part of the roadway into the fortlet has been excavated.

Posts and paving slabs mark the outline of the fortlet buildings. The line of the wall has also been partly reconstructed. Remains from the fortlet, and more information, can be seen in Kinneil Museum.
