Key Facts
- Location: Near Ulm, Germany.
- Total Height: 125 meters (including antenna spire).
- Storage Capacity: Approximately 8,000 metric tons of grain.
- Construction Period: June 2004 to January 2005.

Architectural Design and Construction
The construction of the Schapfen Mill Tower was a rapid project, beginning in June 2004 and reaching completion by January 2005. With a total investment of 6.24 million Euro, the structure was designed to maximize vertical space for industrial utility.
The tower's height is categorized by its structural components: the roof reaches 116 meters (381 ft), while the antenna spire extends the total height to 125 meters (410 ft). For a period following the 2013 demolition of the Henninger Turm, the Schapfen Mill Tower held the title of the tallest operational grain elevator in the world, a record it maintained until the Swissmill Tower in Zürich, Switzerland, was completed in 2016.
Operational Capacity and Technical Specifications
At its core, the tower is a high-efficiency grain elevator—a facility used for the elevation, storage, and handling of bulk grains. The interior is divided into 30 specialized cells, providing a total storage capacity of roughly 8,000 metric tons.
To ensure a steady flow of materials, the facility boasts an intake capacity of 120 tonnes per hour, allowing for rapid processing of harvests.
| Feature | Specification |
|---|---|
| Roof Height | 116 m (381 ft) |
| Total Height (Spire) | 125 m (410 ft) |
| Storage Cells | 30 |
| Total Capacity | ~8,000 metric tons |
| Intake Rate | 120 tonnes/hour |
Sustainable Energy Integration
Beyond its primary function as a silo, the Schapfen Mill Tower incorporates green technology. The south-facing facade is equipped with a photovoltaic system—a method of generating electrical power by converting solar radiation into direct current electricity.
This system utilizes 1,300 CIS solar modules (Copper Indium Selenide), which produce approximately 70,000 kWh of electricity annually. Interestingly, because the modules are mounted vertically rather than at an optimal tilt, the system operates at about 70 percent of its theoretical maximum yield.
