The Asse is a small hill range in the district of Wolfenbüttel in southeastern Lower Saxony with a median height of 200 metres ASL; the highest elevation is the Remlinger Herse with a height of 234 m. There are more than 600 different plants found here; the Asse is mostly covered by trees. It has been inhabited since the 6th millennium BC by farmers coming from the Danube region. For several hundred years, salt has been mined in Asse. One of these mines, Schacht Asse II, is now used to store low- and medium-grade radioactive waste produced by medicine and nuclear power plants.

The Asseburg is a ruined hill castle on the narrow, southern crest of the Asse ridge in the Harz Mountains of Germany, not far from Wolfenbüttel. The castle was built around 1218 by Gunzelin of Wolfenbüttel and his descendants of the House of Asseburg, as a so-called Ganerbenburg, or castle managed and occupied by more than one family or branch. Based on its dimensions, this elongated fortification was the largest hill castle in North Germany and was considered impregnable. Its purpose was to secure the lands around Wolfenbüttel. When Gunzelin refused to swear allegiance to Duke Albert I of Brunswick-Lüneburg, of the House of Welf, in 1255, the latter destroyed Gunzelin's Wolfenbüttel Castle and sieged Gunzelin's son Burchardus de Asseburc (Burchard or Busso of Asseburg) at Asseburg Castle. Burchard was able to withstand during three years, however in 1258 had to relinquish the castle to Duke Albert I. Burchard was then allowed to retreat to Westphalia with his knights, and received a compensation of 400 gold mark for the castle. After Gunzelin's death in 1260, his sons also lost the county of Peine to the bishop of Hildesheim. Asseburg became one of the strongest fortresses in the duchy. In 1330 the dukes had to pledge the castle to the city of Brunswick, which was interested in securing the trade routes below. When Duke Henry IV asked the castle back in 1492, threatening another siege, the garrison set fire on the castle and left. It fell into ruins after it was abandoned.
