Though less known than Hadrian's Wall, the Antonine Wall also played a crucial role in Roman military strategy in Britain. In their attempts to subdue the unruly Picts in Caledonia (now northern Scotland), the Romans encountered serious difficulties and finally settled for a defensive wall running from a little west of Edinburgh to a little north of Glasgow.

The picture above, taken near Falkirk, shows one of the most visible parts of the defense system, a ditch dug to impede marauders: from the botton of the ditch to the top of wall was once an intimidating distance of 30 feet. The wall itself was built largely of turf and has not survived the ravages of erosion very well: the slight rises in the ground in the picture below are what can be seen of the wall.
