The Bismarck Tower featured on the village coat of arms

The Bismarckturm in Oberg stands as a quiet, round sentinel of sandstone on the Lahberg. It is a modest elevation of 11.2 metres, rising 109 metres above sea level. Its presence is not a recent addition to the landscape, but a deliberate construction from the first half of the last century.

In 1915, the local manor owner Hugo Leßmann commissioned the tower to honor the 100th birthday of the former Imperial Chancellor Otto von Bismarck. To realize this tribute, a master builder from Groß Lafferde was hired to work in the Neo-Romanesque style. The result is a sturdy, circular structure built from sandstone.

After the tower was inaccessible, it was declared a heritage monument in 1989. This recognition preceded a renovation that allowed the tower to be accessible again since 1995.

While the tower was built in the 20th century, the village of Oberg has a lineage reaching back much further. The lords of Oberg were prominent figures as early as the 13th century, serving the bishops of Magdeburg and the dukes of Braunschweig-Wolfenbüttel. They governed the frontier of Oebisfelde until 1448, when the last lord of the line, Günter von Oberg, passed away. His grave remains unknown.

In 1952, the village celebrated its 800th anniversary by creating a coat of arms. In a move that cements the tower's status as a landmark, the designers included it in the official heraldry. The shield balances the old and the new: it features the two black diamonds on a gold background from the 1605 records of the noble family, alongside the depiction of the Bismarckturm.
