Hofbrunnwerk, Pumping station in Altstadt-Lehel, Munich, Germany

The Hofbrunnwerk is a water-powered pumping station on the Hirschauterrasse at the north side of the Unterer Hofgarten in Munich's Altstadt. Its pump room sits in the substructure of the Hofgarten arcades, with the turbine chamber adjoining to the north. Water from the Hofbrunnwerkkanal drives Girard turbines that power a pump lifting groundwater from a shaft.

The facility was built between 1615 and 1617 when Maximilian I expanded the original fountain works into a water tower to supply drinking water to the court and nearby city. In 1885, engineers replaced the traditional water wheels with advanced Girard turbines.

The name refers to the Hofbrunnwerk canal, which still drives the facility: water from the canal powers the turbines, while groundwater is lifted from a shaft to feed the Hofgarten fountains. The pump room sits in the substructure of the Hofgarten arcades, the turbine room directly north of it.

The Hofbrunnwerk is not open to visitors: the pump room sits in the substructure of the Hofgarten arcades and the turbine room adjoins it to the north, both closed to the public. The Hofbrunnwerkkanal runs along the Hirschauterrasse on the north side of the Unterer Hofgarten, where the Munich city brooks flow.

The 1885 Girard turbines that replaced the original water wheels are still in place in the turbine chamber north of the pump room. The plant draws groundwater from a shaft, and the energy for lifting it comes from the Hofbrunnwerk canal, which was filled in after 1968 and only reopened in 1991 during the conversion of the old army museum into the State Chancellery.
