Ernst Thälmann Park in Berlin’s Prenzlauer Berg district is far more than just a green space. The approximately 25-hectare site, which was officially inaugurated on April 16, 1986, is today regarded as a unique, listed ensemble of socialist urban planning, a memorial site, and a valuable green oasis for local residents
Where walkers, dog owners, and those seeking relaxation now enjoy nature, the historic IV. Berliner Gasanstalt once stood. For the GDR leadership’s prestigious residential park project, which was to be completed in time for Berlin’s 750th anniversary, the old industrial facilities and gasometers were demolished in 1984 amid public protests.
Ernst Thälmann and his monumental monument

The complex is named after Ernst Thälmann (1886–1944), who was one of the most influential political figures in the Weimar Republic as chairman of the Communist Party of Germany (KPD). After the National Socialists seized power, he spent eleven years in solitary confinement before being murdered in 1944 at the Buchenwald concentration camp. In the GDR, he was glorified as an anti-fascist resistance fighter, while his historical role as a loyal Stalinist was hotly debated after the fall of the Berlin Wall.
The unmissable, monumental Ernst Thälmann monument on Greifswalder Straße commemorates him. The colossal bronze sculpture was created by the Soviet sculptor Lev Kerbel; it is 14 meters tall and weighs around 50 tons. It depicts Thälmann’s bust with a clenched fist in front of a workers’ flag. After reunification, there were heated discussions about tearing it down, but the monument was preserved as a historical artifact and has been a protected historical monument since 2014. An information panel today offers a critical assessment of Thälmann’s biography.
The Kiezteich: A Saved Oasis

The Kiezteich is hidden behind the sparse woodland of Ernst-Thälmann-Park. The artificial pond complex was created in 1985. Over the decades, it has developed into a valuable, protected biotope in the heart of the city. Despite the surrounding concrete, the fenced-in pond is now an important amphibian sanctuary. It provides a home for frogs, toads, dragonflies, and rare birds such as mandarin ducks and kingfishers.
Because the body of water has no natural inflow or outflow, it faced extinction in 2007. The district even planned to fill in the pond due to a lack of funds. Fortunately, a dedicated residents’ initiative prevented this. Since then, volunteer neighbors have maintained the pond on their own and ensure water quality solely through donations. Thus, this urban oasis for people and animals has been preserved.
