Deep dives

Understanding the Schwerbelastungskörper

The Schwerbelastungskörper is a massive concrete cylinder located in Berlin, initially built to test the properties of the soil in relation to proposed monumental architecture from the Nazi era. Constructed from 12,650 tons of concrete, this cylindrical structure was designed to simulate the pressure of larger buildings, such as Hitler's grand plans for a new Berlin, which he envisioned as a cultural capital. Interestingly, this site transformed into a tourist attraction, drawing visitors intrigued by its history as a relic of a failed urban planning scheme. The name itself, which translates to 'heavy load bearing body,' captures its significance as a monument to the architectural ambitions of the Third Reich that, ultimately, went unrealized.
