Grünhirscher Stollen

Silberhütte was once a village in the formerly free mining town of Sankt Andreasberg in the Harz mountains in Germany, but since its merger on 1 November 2011 it has been part of the borough of Braunlage. The name of the village goes back to the silver works that was existed here until 1912 and which smelted the ores from the mines around Sankt Andreasberg. According to Ließmann (2003), the smelting of the ores was carried out here soon after the opening of the Sankt Andreasberg silver mines. These naturally had a raised arsenic content. The silver works was located at the confluence of the Wäschegrundbach and the Sperrlutter - so that there was enough water power to drive the machines in the smeltery. Not only did the smelting workers here have to endure toxic emissions but, even in older accounts, there is talk of the massive nuisance caused by toxic, arsenic-containing, fumes from the smeltery which, in unfavourable weather conditions, swept into the town and occasionally forced the people living there to flee. The first smelting works are recorded at this locality around 1550. At the beginning of the Thirty Years' War, the smeltery was sold and demolished. When the silver mining industry flourished again in the 1680s, a new larger smelting works was built, which - rebuilt and extended several times - was in operation until 1912. In 1836, the responsible mining authority allowed the construction of a separate arsenic works on the Silberhütte site. In addition to arsenic trioxide, a toxic white powder, arsenic glass was also produced. Handling the powdery poison was very difficult. The workers were only sent into the chimneys to sweep the arsenic with a damp cloth in front of their faces - without a special bonus, hardly any worker was willing to sweep the arsenic dust. A contemporary report by master smelter, Seidensticker, stated that, "the arsenic trioxide produced cannot be weighed because this would cause disproportionately high costs and endanger workers' health more than the rest of the arsenic work put together."

Sankt Andreasberg is a former town in the district of Goslar, in Lower Saxony, Germany. Since 1 November 2011, it is part of the town Braunlage. It is situated in the Harz, approximately 7 km west of Braunlage proper, and 20 km east of Osterode am Harz.

The Samson Pit or Samson Mine (German: Grube Samson) is an historic silver mine in Sankt Andreasberg in the Upper Harz region of central Germany.The pit has one of the oldest man engines in the world still working and it can be seen in operation during guided tours. The man engine, installed in the Samson Pit in 1837, used to be driven by the water power of the Rehberg Ditch (Rehberger Graben). The start of this ditch is the Oderteich reservoir, which is part of the Upper Harz Water Regale. The large water wheel (with a 12 m diameter), which drove the man engine until 1922, is only powered by water today for demonstration purposes; an electric motor has taken over the operation of the man engine.

The Sieberstollen is an adit (German: Wasserlösungsstollen) for water drainage in Sankt Andreasberg, in the Harz mountains. It was created during mining in the Upper Harz and named after the river Sieber into which it discharges its water. The opening position is in the Sieber Valley.The first 11.7 km of the 13.1 km adit forms part of the Upper Harz Water Regale and has been declared UNESCO World Heritage Site in 2010.

The Kuppe is a mountain in the Harz that lies north of Sankt Andreasberg in the district of Goslar in the German state of Lower Saxony. It is 729.1 metres high and is connected to the Jordanshöhe in the west.

The Roter Bär Pit (German: Grube Roter Bär) in Sankt Andreasberg in the Upper Harz is an iron ore mine that was worked from about 1800 until the 1860s. Today it is operated as a show mine under the name of Roter Bär Pit Educational Mine by the Sankt Andreasberg Society for History and Archaeology (Sankt Andreasberger Verein für Geschichte und Altertumskunde). The name Roter Bär means "Red Bear". In line with historical practice the funds required to restore the historic mine were raised through the formation of a mining trades union and issue of share certificates.

The Jordanshöhe is a mountain, roughly 723 m above sea level (NHN), in the Harz in central Germany. It lies north of the town of Sankt Andreasberg in the district of Goslar in Lower Saxony. To the west is the Kuppe. On the mountain there is the Jordanshöhe youth hostel and the Jordanshöhe nature trail (Gesteinskundlichen Lehrpfad Jordanshöhe).

The Koboltstaler Köpfe ("Kobolt Valley Peaks") are a group of three mountains, that rise southwest of Sankt Andreasberg and east of Sieber in the district of Göttingen in Lower Saxony. The highest of the three peaks is 673 metres high. The other two summits lie roughly 350 metres east and south of the main peak respectively and are ony a few metres lower. The Koboltstaler Köpfe are mainly covered by pine forest and accessible on all sides by forest roads. To the southwest runs a mountain ridge, the Gödeckenkopf or Gödeckekopf, whose crest lies between 600 and 650 metres high. It is bounded to the west by the Mittleren Gödeckental and to the east by the Kleinen Gödeckental. To the southwest it falls away steeply towards the Großes Gödeckental valley.

The Sankt Andreasberg Observatory, also called Harz Observatory, is a project of the charitable society Sternwarte Sankt Andreasberg e. V., which translates into Sankt Andreasberg Observatory registered society. It was opened in August 2014 and is supposed to become the first completely barrier free Observatory in Germany. The society's expressive goal is to make the sky accessible to all people, whether they are disabled or not. Celestial observation, lectures and Workshops convey general astronomical knowledge to visitors.

Kleine Kulmke is river of Lower Saxony, Germany, in the Harz Mountains, a tributary of the Große Kulmke. The Kleine Kulmke rises at a height of 690 m near the Schmierplatz on the Auf dem Acker ridge north-northeast of Sieber in the district of Göttingen and flows initially southwards to its confluence with the Verlorene Kulmke ("Lost Kulmke", 428 m), from which it is separated by the Kleiner Wurzelnberg hill. It then flows in a southwest to south-southwest direction before uniting with the Große Kulmke ("Big Kulmke") after 3.4 km (2.1 mi) at a height of 392 m. The valley of the Kleine Kulmke partly belongs to the Sieber Valley (Siebertal) nature reserve.

Schadenbeek is a small river of Lower Saxony, Germany. It flows into the Krumme Lutter north of Bad Lauterberg.

At 893 metres (2,930 feet) above sea level, the Rehberg in the Harz mountains is the fourth highest mountain in the German state of Lower Saxony, and the fifth-highest in the Harz.
