The district of Bieselberg is on the eastern edge of the municipal area and, with around 1,000 inhabitants, is the third largest district after Schömberg and Langenbrand.
In 1180, Bieselsberg was first mentioned as "Böselsberg" in the donation book of the Hirsau monastery. In 1603, the Margrave of Baden sold the town, which he now owned, to the Duchy of Württemberg. The original settlement form as a Waldhufendorf is still recognizable today. However, a major fire in 1885 destroyed the houses from the wind farm to the smithy, including the town hall. As part of the reconstruction, the forest hoof structure in this area was largely lost.
As early as 1600, there must have been a chapel in Bieselsberg dedicated to "our dear wife". The original construction is believed to be in the 14th century. The church was enlarged in 1744. In 1896 and 1897 it was renovated in its present form.
A drastic event for Bieselsberg was the failure of sales negotiations for the inn "Zum Löwen" in 1887. The Erfurt businessman Hugo Römpler wanted to acquire it in order to set up a convalescent home there for people suffering from lung diseases. As a result, not Bieselsberg but Schömberg with its sanatoriums developed into a health resort known worldwide.
With the incorporation into the overall municipality of Schömberg, Bieselsberg gave up self-government in 1975. The community daycare center "Buddelflink" and the Protestant parish have found their home in the community center. A special feature is the observatory, which went into operation in 2003 and offers regular guided tours. The Black Forest specialty hike offered every year from 2007 to 2017 was also known far beyond the borders of the small town.
