The Krayenburg was a castle situated on the Krayenberg hill in Germany, having the townships of Tiefenort and Merkers-Kieselbach at its foot, and overlooking an extensive section of the Werratal. On 31 August 786 Charlemagne gave the village of Dorndorf and all of its belongings to Hersfeld Abbey; the abbey built the Krayenburg to protect it. The castle changed ownership repeatedly. It was owned by Graf Adam von Beichlingen, who died on 7 August 1538 and is buried in the church in Tiefenort. The Thirty Years' War started the destruction of the castle when Croatian troops (under Johann Ludwig Hektor von Isolani) captured the Krayenburg. However, it continued to play an important role in German history until the 19th century. Johann Wolfgang von Goethe visited the castle in 1782, the year he was ennobled. The castle was originally very large, once larger than Wartburg Castle. The ruins have been restored and are open to visitors; there is a restaurant with hotel on the former site. A tower allows a wide view into the Werratal.

The Krayenberg is a 431-metre (1,414 ft) hill near Tiefenort, Germany. Since 500 BCE it was a rampart and served as a refuge for the central part of the Werratal. It became important for German history due to the Krayenburg, which was built on its top after 786, and destroyed starting with the Thirty Years' War. Today, the well-maintained ruins, a restaurant and a hotel define a tourist location in the Werratal.

The Menzengraben mining accident was the explosion of a large pocket of carbon dioxide in a salt mine in Menzengraben, East Germany, on 7 July 1953. During a planned, nightly explosives detonation in the mine, an unusually large pocket of pressurized carbon dioxide was suddenly released, resulting in the ejection of large blocks of salt through the mine shaft at very high velocities. The expanding gas as well as the blocks of salt demolished the building above the mine shaft, resulting in blocks of concrete being ejected as well. Three died as a consequence, one from being hit by debris, two from asphyxiation.
