Elevated water reservoir on the Lindener Berg
The elevated water reservoir in Hanover is a listed elevated reservoir from the 19th century. The building, built in the style of a medieval fortress , supplied the city's residents for the first time through a modern Hanoverian drinking water pipe. Even today, the building is one of the most important water supply structures in northern Germany . From the roof terrace , which was originally open to the public, visitors were able to look far over the Calenberger Land through an additional observation tower . Today (as of March 2015) a large number of trees conceals the monumental long-distance effect of the building, and the terrace is only temporarily open to evening visitors to the public observatory . The location is the highest point at the end of the street Am Lindener Berge 27 , on the " local mountain " of the Lower Saxony state capital , the Lindener Berg in the Hanoverian district of Linden-Süd , which protrudes 89 meters above sea level .
History and description
The structure was created in connection with the Ricklinger waterworks system , from where a pump house (demolished in 1974) in the Ricklinger Masch on Stammestrasse was supposed to direct fresh water to the highest point of the Lindener Berg, from there to the central water supply network of Hanover, as well as initially only to be continued in a few streets in Linden . The engineer Rudolph Berg was responsible for the technology of Hanover's first modern aqueduct . For the construction of the proposed water elevated tank, 42 meters above the jam mirror the leash , but had to first the 1825 by Georg Ludwig Friedrich Laves for the entrepreneur Johann Egestorff on the hill built Berggasthaus be canceled. After the hilltop had been raised up, the huge one was built by the Hanoverian architect and master mason A. Strasser in the years from 1876 to 1878 according to plans by the architect and head of the building construction department of the Hanover City Building Office , Otto Wilsdorff , and his colleague A. Bues , " Wasserburg " with around 10,000 cubic meters of drinking water .
The fortress-like structure , reminiscent of a fortress , rests on a sloping, around 50 × 80 meter wide terrace made of natural stone blocks , above which a 40 × 80 meter wide and around 8.5 meter high container rises. Which also sloped and plastered exterior walls are buttresses strengthened -like templates and chanted and rise against on arches resting from bricks brick flat roof - Attica , which as a medieval battlement recalls. The structure gives a repellent impression on three sides.
The display side, however, which gave visitors a view of Linden and Hanover to the east, was designed more inviting and in the style of the Hanover architecture school . A middle, two-storey fort building in the neo-Gothic style was pushed forward between two polygonal “ pavilions ” set up symmetrically in front of the corners of the “moated castle” as corner towers . This richer architectural forms and their materials were repeated in the built-up in the middle of the walk-elevated tank, tower-like attachment with a castle tower . A lookout tower on the top roof terrace, which was initially publicly accessible to the public , rose above the porches and superstructures that served as an apartment for the water master and, for example, for gate valves , stairs and chimneys .
The completion of the elevated tank marks the beginning of a whole series of subsequent technical buildings in Hanover, so for
- the Ricklingen waterworks from 1878;
- the (lost) river water art from the 1890s in front of the Leineschloss ;
- the water tower in Misburg ;
- and the one at Vahrenwalder Straße 267 ;
- and the waterworks in Misburg from 1926.
After an aerial bomb damaged the elevated tank during the air raids on Hanover in World War II , the roof structure was simplified, but without the observation tower, restored.
In 1977 the container was found to be leaking and was taken out of service. However, after the costs for a demolition and the then complete new building had been weighed against the costs for a conversion and restoration of the listed building, the container building was opened from above and completely cleared out. Above all, the entire technical interior was replaced by the installation of two reinforced concrete tubs, and later the roof was closed again, slightly raised. Since 1983 the building could then be used again as an expansion tank, but now with a capacity of 13,000 cubic meters.
