We have got to thank the Romans for viniculture who did not want to do
without this noble drink far away from Rome. This is why they took vines
with them for growing on the Rhine. It should take years before they
returned back home, some of them stayed here to get married and a family
in Rheinbrohl where the limes should begin for protection of the
roman empire against its enemies. Even Hadrian (117-138), ruler of the
worldwide roman empire travelled from Rome on the Rhine to visit
the border rampart. They made Jupiter, the Supreme Being, a sacrificial
offering which happened on the "Monte Jup". As the emperor was present
this sacrifice was of considerable significance. The forefathers of the
today´s population in Rheinbrohl were astonished when Hadrian went to
the sacrificial altar "Monte Jup" surrounded by his retinue. According
to tradition there was a small temple on this hill. Here the Romans made
sacrificial offerings to their Supreme Being. This is the explanation of
the name of the hill "Mons Jovis" later called "Monte Jup".
"Der nasse Zehnt"
There is a centuries-old relation between Kaiserswerth and Rheinbrohl.
The Kaiserswerther diocese had in Rheinbrohl their own yard, the
patronage right and the right on the "Nasser Zehnt" in those days.
These rights mean, that the dean of the "Suitbertus" Church in Rheinbrohl
got the tenth part of the wine of the "diocese" of Rheinbrohl.
