Can you hear that rhythmic splashing? That is the sound of history turning at the Wasserrad in Erfurt. It is a story of ingenuity and perseverance. Today, we stand before the Neue Mühle. It is more than just a mill. It is a living testament to Erfurt’s industrious past.
Imagine Erfurt centuries ago. Over 60 watermills harnessed the power of the Gera River’s arms. These mills were essential to the city’s economy. The Neue Mühle stands as the last functional watermill in Erfurt’s old town. Its origins trace back to the 13th century. Back then, it was known by various names like Hirschmühle and Martinsmühle. In 1259, it was even listed as “molendium comitis” noting its owner. He was the Count von Gleichen.
However, disaster struck in 1736. A fire engulfed the mill and 70 nearby houses. The mill was rebuilt a year later. It was then christened the Neue Mühle meaning New Mill. In 1895, a significant upgrade occurred. The Zuppinger water wheel was installed. Carl Köhler modernized the mill by adding roller stands. For a time, it was called Kunstmühle or Art Mill.
Heinrich Gruhn, the last miller, ran the mill until its sale to the city in 1982. This mill is preserved in its original state. It showcases the technology of the late 19th century. That is why the Wasserrad remains fully operational.
Step inside and witness the ingenuity of the past. Marvel at the Zuppinger water wheel. This wheel is named after the Swiss engineer Zuppinger. This impressive structure is five meters in diameter. It rotates at ten revolutions per minute. This wheel alone provided the power for the mill’s machinery. It generated about 30 horsepower. To operate the mill, it needed 3,000 liters of water per second. The water rights were established to fairly manage the water distribution among the mills.
In the early 1950s, a water turbine was added. It boosted the total output to about 47 horsepower. Since 1996, the Wasserrad has contributed to the building’s power. It generates electricity from the Gera River. From 1996 to 2011, it produced 289,164.0 kWh.
The Wasserrad is now visible through glass. This allows visitors to appreciate the wheel’s design. Approximately 10,000 people visit the mill and marvel at the Wasserrad each year. The Wasserrad stands as a symbol. It is a symbol of Erfurt’s past and the enduring power of innovation. As the wheel turns, so does our understanding of history.
