Silo Tower Basel, Grain elevator in Kleinhüningen, Basel, Switzerland

Silo Tower is a concrete structure next to the Rhine harbor at Kleinhueningen with a viewing platform at 52 meters (170 feet) high. The platform is fitted with telescopes and informational maps that reveal details about harbor activities and the surrounding landscape.

The structure was built in 1923 for a Swiss shipping company and served as a key facility for the region's grain trade. It demonstrates the importance that river commerce held for Basel's economic development.

The location shows how commerce and river trade shaped Basel's growth. Today, visitors can sense how the harbor remains central to understanding the city's connection with its neighbors across the Rhine.

The platform is reached by an internal lift whose machinery sits in the turret above the terrace, not by stairs. It is open to the public during harbour tours run by the port authorities and at events such as the summer open-air cinema of the neue kino Basel. The terrace was renovated in 2006 after its collapse risk.

The tower does not stand on the tri-border point: the actual Dreiländereck lies in the Rhine, just south of the Dreiländerbrücke, while the symbolic marker is a short walk from the silo. From the 45-metre terrace you still see Switzerland, Germany and France at once. The silo's viewing platform opened in 1926 for the first inland navigation exhibition, reached by a temporary outside lift.
