Sperberhaier dam house
The Sperberhaier Dammhaus ( also only Dammhaus according to the information board ) is part of the mountain and university town of Clausthal-Zellerfeld and is located on the Dammgraben in the Upper Harz Mountains . Until 2015, the Sperberhaier Dammhaus belonged to the then independent mining town of Altenau .
It was built together with the Sperberhaier dam in the years 1732–1734, which closed a gap in the Upper Harz water shelf and bridged a shallow valley basin at a height of up to 16 m. Most of the original house has been preserved.
The dam house was originally built for the miners who used it as a changing room and prayer house. Later it was used as an official residence for the trench keeper. In the further course the dam house, also known under the names "The foal house on the Sperberhaier" and "Sperberhaier Zechenhaus", served to supply forest workers and hikers.
Due to the construction of the Harz-Hochstraße B 242 and the B 498 , which branches off Höhe Dammhaus on the one hand to Altenau and on the other to Osterode , it is now on a busy street and has developed into a popular excursion restaurant that can also be reached by public buses .
