The Obertorer Mühlbach flows through the area of the Obere Au sports facilities. In 2019, the stream has been relocated, recultivated and relaunched as a local recreation area.
The Obertorer Mühlbach was relocated over a length of about 550 m. The course of the stream begins at the end of the intersection Rossboden- / Pulvermühlestrasse and ends at the old bus turning point in the Oberen Au. The first water will has flown through the ecologically designed, renaturalised riverbed in mid-April 2019. The amount of water has been reduced and the stream can therefore also be entered.
The renaturalised riverbed thus enables habitats for animals and a local recreation area for walkers and cyclists. The new boccia and skate park sports facilities in Chur are located right next to the inviting banks of the Mühlbach stream. Curved pedestrian bridges allow safe crossing of the stream and a steps along the shore at the skate park invites you to linger.
In the area of the existing indoor riding arena, the Mühlbach runs temporary underground over a length of 30 metres until the indoor riding arena is dismantled in 2023.
