Surprisingly, a monolith with a memorial plaque stands on the slope. At first you might think that Prince Otto von Bismarck was banished from the center of Vienenburg - far from it. It is Albert Schloenbach (1811-1877), he was an important senior saltworks inspector and geologist who was intensively involved in researching the Harly forest. His work contributed significantly to the geological understanding of the region. In honor of his services, a memorial plaque was erected in Harly, which is attached to his favorite research area. (Source: Regionalheute). In Harly forest there is also an impressive sequoia tree, which was planted in 1880 by the then district forester. This tree has a circumference of 4.45 meters and was declared a natural monument in 1976. The giant sequoia tree is called 'Lisa von Harly' in Harly (Sequoiadendron giganteum). Nearby is the Kräuter-August Cave, which is also worth discovering because of the legend, before heading up to the Harly Tower. Although the name cave is a bit over-promising... have fun exploring. 🙋♂️

Otto Eduard Leopold von Bismarck-Schönhausen was the first Chancellor of the German Empire. There is also a large, little-known memorial stone here in beautiful Harly. This granite block comes from the quarry in Bad Harzburg and was set at the suggestion of the two volunteers from Hau and Count Kolata. This stone stands with its base as deep in the earth as above, in its foundation. When the foundation stone was laid, a certificate was lowered, which was decorated with a few coins. This stone was donated in 1885 for Bismarck's 70th birthday. (Source: https://www.geocaching.com)
