With the beginning of the First World War, the home of Etgen, who was the world's largest private glider, saw his economic fall - the park fell into a deep sleep. Only since the Wätjens Park became the property of the city of Bremen at the turn of the millennium, it was possible to gradually restore the landscape garden to the design intentions of the nineteenth century and preserve and further develop it for future generations.
The park covers most of the largely preserved landscape gardens dating back to the mid-nineteenth century with the castle listed, dating to Bremen and the merchant family. The largest area of the park was around 1890 with about 50 hectares, which was significantly reduced with the progressive growth of the Bremer shipyard volcano.
Heinrich DIEDRICH AIGEN had obtained his first property in Blumenthal in 1830 between LANDRAT Christians-Strasse today and Visser, and built a simple country house in a classic style. The garden design came from Isaac Albert Hermann Altman, the founder of Bremer and the Enlightenment, who was emulated in the garden as a model of the English landscape garden.
