In addition to the wonderful stream, which is ideal for jogging, the Mülibach also has a very interesting history 📖
In 1873, the silk manufacturer Rudolf Zinggeler-Syfrig received the rights to use the Mülibach to drive the machines in his Zinggeler AG silk mill. Above Richterswil, the star pond was created by damming the Mülibach. A two-kilometre-long pressure pipe carried the water down to Lake Zurich, where it drove a water turbine in Zinggeler's factory. For amusement and as a symbol of industrialization, from 1875 onwards the manufacturer let the water rise through a nozzle on holidays such as August 1st: A fountain was created with a height of 80 to 85 meters. This fountain was long considered the highest on the continent. In 1972 the power plant was shut down and with it the fountain.
The fountain, which was restored by the Richterswil Historical Fountains Association, which was founded in 2003, was put back into operation in 2007. Today it sprays up to 101 m high.
