Limes 
Description
The Limes form part of the UNESCO Roman frontier world heritage site that includes Hadrian's wall. The Limes performed a similar function to the wall, protecting the Northern border of the Roman empire from the tribes further north. Unlike Hadrian's wall the Limes was built using earth banks and Wooden fences, so very little of the actual wall, other than some raised earth mounds, exist, but where they do, behind Saalburg fort, they provide a good insight into the defences in this part of the Roman empire.
