Hammermühle, Gristmill in Biebrich, Germany

The Hammermühle is a mill in Biebrich, Wiesbaden, situated near the Salzbach river. The building was converted into residential apartments and continues to shape the character of this area today.

The mill was built in 1690 after an iron hammer facility was destroyed. It later became a center for grain processing under Bernhard May's management and has a long industrial history.

Bernhard May ran the mill as a meeting place he called the "Herberge der Gerechtigkeit", receiving the revolutionary Robert Blum, pianist Clara Schumann and composer Johannes Brahms. May took part in the Hambach Festival in 1832 and the Frankfurt Vorparlament in 1848.

The building is now privately owned and houses apartments accessible via streets named 'An der Hammermühle' and 'Bernhard-May-Straße'. Visitors can walk through the area at any time and view the exterior of the complex.

Of the many mills once standing in the Salzbachtal, the Hammermühle is the only one still preserved. Its owner Bernhard May, a participant in the 1832 Hambach Festival, lost the garrison bread contract when Duke Wilhelm I of Nassau withdrew it for political reasons.
