Esterliturm, Concrete observation tower in Lenzburg, Switzerland.
Esterliturm is an observation tower in Lenzburg made of stacked concrete pipe segments reaching 48 meters high. The viewing platform at the top offers views across the rolling countryside of the Aargau region.
The tower was built by the local community in 1974 as an observation structure for the growing town of Lenzburg. Its concrete pipe construction was an innovative building method for that period.
The tower serves as a central gathering point where visitors and locals connect while observing the Swiss landscapes from the viewing platform.
The tower is accessible year-round and open at all times without restrictions. Space on the viewing platform is limited, so it fills quickly on clear days with good visibility.
The structure is made from 19 concrete pipe segments stacked vertically like an industrial column. This assembly method creates a distinctive cylindrical form that makes it stand out as an unusual piece of architecture in the landscape.
