The Pegelhaus in the Koblenz Rhine complex, now
used as a restaurant, was originally built as a Rhine crane. The building dates
from the 17th century. Elector Lothar von Metternich had the octagonal building
with its profiled base built from 1609 to 1611 as a Rhine crane with the
collaboration of Johann Pasqualini, master builder of the Jülich fortress. The
building was used in this function until 1839. After the crane mechanics had
been removed, it was used primarily as a gauging station for various business
purposes. To the right of the entrance to today's café and restaurant with
glazed roof, the flood marks from the various centuries can be seen.
On the left side there is a blue gauge clock. The
water level measured at the water gauge house is one of 22 water gauges
relevant for Rhine navigation measured along the Rhine.
