northern border of the Roman Empire
In the early days of the Christian
era the northern border of the Roman empire was mainly defined
by the rivers Rhine, Main and Danube. At the end of the first
century AD parts of the border line were extended northwards.
A new border was set by hundreds of kilometers of ditches and
mounds fortified with wooden palisades. Castles and watchtowers
at regular intervals were build to control the traffic entering
the empire. This was in particular the case from Bad Hönningen
(on the river Rhine, south of Cologne, Germany), across the Taunus
mountains towards Miltenberg on the river Main, and further to
Einig (close to Kelheim on the river Danube). This fortified
border line is known as the Limes Germanicus (see map
above and images below). Due to large scale excavations it has
been possible to trace the ancient Limes quite exactly. The website
of the Verein
Deutsche Limes-Strasse gives many details.
Limes cycle route: 4100 km from North Sea to Black Sea
For the years 2008 and 2009 Henro de Witt and I have chosen for cycling along the border of the Roman Empire from Katwijk aan Zee to Constanta (see map above). We have covered the first half, from Katwijk to Wien, in July 2008. The second part, from Wien to Constanta followed in April/May 2009. Detailed descriptions with maps and photos are given on the next pages (click bike-button top right). For easy reference, the Limes route is described from west to east, although we have cycled the first part of the route in opposite direction (see bike transport).
