The Bridgeness Slab is a Roman distance slab created around 142 CE marking a portion of the Antonine Wall built by the Second Legion.[1] It is regarded as the most detailed and best preserved of the Scottish distance slabs.[2] The sandstone tablet was found at Bridgeness in Bo'ness, Scotland in 1868 on a promontory close to Harbour Road.[3] The original is in the National Museum of Scotland in Edinburgh, while a replica is near the site of its discovery.
