It is located at the northern foot of the Harz mountain range and Harz National Park, about 4 kilometres (2.5 mi) north of the town of Ilsenburg. The small Ecker river in the west, a tributary of the Oker, forms the border with the town of Bad Harzburg in Lower Saxony.
The Stapelburg estates passed to the Prince-Bishops of Halberstadt in 1394 and were temporarily given in pawn to the Counts of Stolberg. The settlement emerged in the second half of the 16th century from the outlying estate (Vorwerk) of Bilenshausen or Bilashausen, that had been established by the former Halberstadt councillor Heinrich von Bila (1535–1584) at the foot of medieval castle. After lengthy negotiations, castle and village were finally purchased by Count Christian Ernest of Stolberg-Wernigerode in 1722.
Reconstructed Jungborn pavillon
The meadows in the Ecker valley south of the village were the site of the Jungborn destination spa, founded in 1896 by Adolf Just, which hosted notable guests like Franz Kafka in July 1912. As the Ecker formed part of the inner German border after World War II, the facility was closed and finally demolished in 1964 to make space for border fortifications.
