Only the main building of Heleneborg estate survived until today and can be found at the beginning of Söder Mälarstrand, close to Pålsundsbron. This is all that is left of what used to be a large estate with a rich history. In the 17th century it belonged to the Swedish tobacco manufacturing company (Tobakskompaniet) and used for tobacco production. In the 18th century it was owned by the clay pipes’ producer who lost his entire fortune trying to find gold in the Swedish silver mines. But the most famous story is from the 19th century and closely connected to the invention of dynamite. 

In the 1860s manufacturer and inventor Immanuel Nobel rented these premises. His son Alfred and Alfred's brothers run their early experiments with explosive nitroglycerin here. Alfred was convinced that nitroglycerine had a big future, but his knowledge of how to handle the explosive was still limited. On September 3, 1864 a tragic accidental explosion occurred killing his youngest brother Emil Oskar and several other people. As a consequence, all manufacture of nitroglycerine was forbidden within the Stockholm boundaries and Alfred moved his experiments to the Vinterviken area. It was surrounded by cliffs and therefore more suitable for the dangerous experiments.
