The Odenwald area of Germany was once a Roman frontier – just like Falkirk district back in Scotland.
You can visit a number of Roman sites around the Odenwald area, including a replica watch-tower, just outside the town of Erbach. Watch-towers like this would be part of the frontier system built by the Romans.
A report on the Odenwald Association’s visit to Limes sites in 2018 is on The Falkirk Herald website. There are also pictures from the visit below.
