run out of the northern part of the Eifel to
Colonia Claudia Ara
Agrippinensum (present-day Cologne) and was
built to provide Cologne with fresh, clear drinking water. To get to Cologne
the Roman engineers needed a steady angle. A great
achievement, laying out the right route without having
at one's disposal aerial photographies, exact maps and
electronic devices. The construction was almost entirely below
ground and the flow of the water was produced entirely by gravity.
A few bridges, including one up to 1.400 m in length, were needed to pass
over valleys. Unlike some of the other famous Roman aqueducts, the Eifel
aqueduct was specifically designed to minimize the above-ground portion to
protect it from damage and freezing.
At Vussem one can see how such an aqueduct looked
like (1st photo >>>). In
Buschhoven, near Bonn, a small section of
the aqueduct is preserved (2nd photo >>>).
