The chandelier hall is the name of a three-sided and approximately 4.60 meter high room in a building in the Cologne sewer system . For the inauguration in 1890, the room was decorated with two chandeliers with six candles each because Kaiser Wilhelm II was invited. At the end of the 1980s, the rotten chandeliers were replaced by a white-painted electric chandelier that was faithfully recreated especially for this purpose.
The exit to the chandelier hall is located under a green-painted hydraulic floor flap in the green area near the northern intersection of Theodor-Heuss-Ring and Clever Strasse in Neustadt-Nord .
history
During the development of the new city in 1881 by city architect was Josef Stubben and city architect Carl Steuernagel planned a sewage system for old and new. The sewer system was then considered to be technically exemplary.
The concept envisaged a low collector near the banks of the Rhine , a parallel, higher-lying high collector and a ring canal for draining the old town. In the chandelier hall, the high collectors and the ring canal were brought together and the wastewater was led north to the first Cologne sewage treatment plant under Clever and Amsterdamer Strasse . While the ring canal leads through the chandelier hall in an open arch, the wastewater from the high-level collector is directed into the ring canal from below.
Technically speaking, the space is also a so-called “ rain relief structure ”. In heavy rain, the ring canal overflows over the wall and runs through the room into another canal directly to the Rhine.
A stone plaque in the chandelier hall reminds of the commissioning by Mayor Friedrich Wilhelm von Becker in 1890.
present
The structure was not damaged in World War II . Today it is in excellent condition and still serves its original purpose. However, the wastewater is now directed to the sewage works on the right bank of the Rhine in Stammheim .
The Cologne city drainage company has been organizing tours and concerts in the chandelier hall since 2000. The special acoustics of the three confluent sewer tubes and the adjacent vaulted rooms are used. In principle, staying in the chandelier room is only permitted with permanent measurement of the gas parameters. The chandelier hall is since 24 June 2004 monument .
