Schapfen Mill Tower, Modern grain silo tower in Ulm, Germany.

The Schapfen Mill Tower is a grain storage facility in Ulm that combines industrial function with contemporary architecture. The structure features multiple storage compartments stacked vertically to maximize storage capacity within the building's footprint.

Construction of the Schapfen Mill Tower began in 2004 and was completed in 2005. After the Henninger Turm was demolished in 2013, it became the tallest operational grain elevator in the world, holding that title until the Swissmill Tower in Zürich was completed in 2016.

The tower is named after the Schapfenmühle, the mill it serves near Ulm. Its 30 cells hold about 8,000 metric tons of grain, and the intake runs at 120 tonnes per hour, so the building works as a working grain store rather than a monument. The south facade carries 1,300 CIS solar modules producing about 70,000 kWh a year.

The building is clearly visible from street level and stands out due to its height and modern design. Visitors can view the structure from multiple angles around the area to appreciate its industrial form and contemporary appearance.

The south facade carries 1,300 CIS solar modules producing about 70,000 kWh a year, yet because they are mounted vertically the array reaches only about 70 percent of its theoretical yield. The panels are a detail to look for on the tower's sunlit side.
