Sudmerberg

The Gelmke is a small stream, roughly 6 kilometres (3.7 mi) long, and right-hand tributary of the Abzucht in Lower Saxony, Germany. The stream flows through part of the town of Goslar.

The Zwinger in Goslar is a battery tower that is part of the fortifications of the old imperial city of Goslar, Germany. It is located on the Thomaswall in the south of the town and was built in 1517. On this side Goslar was strongly dominated by the nearby hill of Rammelsberg, which would have made a good location for positioning enemy guns in the event of an attack on the town; the town fortifications therefore needed the extra protection of a strong battery tower at this point. The stonework of Goslar's Zwinger was predominantly made of sandstone quarried from the Sudmerberg northeast of Goslar and mortared with burnt lime. Because lime burning was still in not fully developed, the builders mixed the mortar with horsehair, quark, goat's milk and ox blood to harden it fully. Immediately under the corbelling are two sandstone tablets in the wall bearing the coats of arms of the German Empire and the town of Goslar and the inscription "Anno dm M D X V II". The original conical roof was dismantled in 1857. With a wall thickness at the base of 6.5 metres, a diameter of 26 metres and a height of 20 metres, the Zwinger is one of the strongest surviving and utilised defensive towers in Europe. The Goslar Zwinger has been privately owned since 1 August 1936. Today it houses a restaurant on the ground floor, three holiday apartments on the middle floor and a small museum of medieval weapons, armour and torture implements on the top floor.

Oker is a borough (Stadtteil) of Goslar in Lower Saxony, Germany. Since 1952 a mining town in its own right within Wolfenbüttel district, it was incorporated into the Goslar municipality on 1 July 1972.

Goslar (German pronunciation: [ˈɡɔslaʁ]; Eastphalian: Goslär) is a historic town in Lower Saxony, Germany. It is the administrative centre of the district of Goslar and is located on the northwestern slopes of the Harz mountain range. The Old Town of Goslar and the Mines of Rammelsberg are UNESCO World Heritage Sites for their millenium-long testimony to the history of ore mining and their political importance for the Holy Roman Empire and Hanseatic League. Each year Goslar awards the Kaiserring to an international artist, called the "Nobel Prize" of the art world.

The church known as Goslar Cathedral (German: Goslarer Dom) was a collegiate church dedicated to St. Simon and St. Jude in the town of Goslar, Germany. It was built between 1040 and 1050 as part of the Imperial Palace district. The church building was demolished in 1819–1822; today, only the porch of the north portal is preserved. It was a church of Benedictine canons. The term Dom, a German synecdoche used for collegiate churches and cathedrals alike, is often uniformly translated as 'cathedral' into English, even though this collegiate church was never the seat of a bishop.

The Imperial Palace of Goslar (German: Kaiserpfalz Goslar) is a historical building complex at the foot of the Rammelsberg hill in the south of the town of Goslar north of the Harz mountains, central Germany. It covers an area of about 340 by 180 metres. The palace grounds originally included the Kaiserhaus, the old collegiate church of St. Simon and St. Jude, the palace chapel of St. Ulrich and the Church of Our Lady (Liebfrauenkirche). The Kaiserhaus, which has been extensively restored in the late 19th century, was a favourite imperial residence, especially for the Salian emperors. As early as the 11th century, the buildings of the imperial palace had already so impressed the chronicler Lambert of Hersfeld that he described it as the "most famous residence in the empire". Since 1992, the palace site, together with the Goslar's Old Town and the Rammelsberg has been a UNESCO World Heritage Site because of its millennium-long association with mining and testimony to the exchange and advancement of mining technology throughout history.

Goslar (German pronunciation: [ˈɡɔslaʁ]) is a district in Lower Saxony, Germany. It is bounded by (from the south and clockwise) the districts of Göttingen, Northeim, Hildesheim and Wolfenbüttel, the city of Salzgitter, and by the states of Saxony-Anhalt (district of Harz) and Thuringia (Nordhausen).

The Gose is a small river in Lower Saxony, Germany. It is a left tributary of the Abzucht. The river is 7.1 kilometres (4.4 mi) long with a drainage basin of 10 km2 (3.9 sq mi). Its source lies north of Auerhahn in the Harz Mountains, on the eastern slopes of Bocksberg. The river runs towards the northeast through a steep and narrow valley and meets the Abzucht on the western edge of Goslar, which is named after the river. Its water was once used in the brewing of the traditional Gose beer.

The Treppenstein is a rock formation in the Oker valley in the Harz mountains of central Germany. It lies on the trail from the Romkerhall Waterfall to the Kästeklippen. The rocks consist of granite and have clearly undergone so-called "wool sack weathering" (Wollsackverwitterung).The Treppenstein is a popular destination and part of the system of checkpoints (no. 117) in the Harzer Wandernadel hiking trail network. The summit has safety railings and may be climbed using steps hacked out of the rock and flights of stairs attached to the rocks. From the summit there is a view towards the west. In addition, part of the rock formation, the Kleine Treppenstein is used for rock climbing. The routes here are rated as Grade VI (UIAA).

The Rammelsberg is a mountain, 635 metres (2,083 ft) high, on the northern edge of the Harz range, south of the historic town of Goslar in the North German state of Lower Saxony. The mountain is the location of an important silver, copper, and lead mine. When it closed in 1988, it had been the only mine still working continuously for over 1,000 years. Because of its long history of mining and testimony to the advancement and exchange of technology over many centuries, the visitor mine of Rammelsberg was inscribed as a UNESCO World Heritage Site in 1992.

The Kästeklippen, often shortened to Käste, is a rocky tor above the Oker valley in the Upper Harz mountains of central Germany. It lies at a height of 602 m above NN. Near the Käste are other similar granite rock formations such as the Hexenküche ("Witch's Kitchen"), Mausefalle ("Mousetrap"), Feigenbaumklippe and the Treppenstein. Next to the observation platform is a protruding rock which resembles the face of an old man and is called Der Alte vom Berge ("Old Man of the Mountain"). The rocks consist of granite "wool sacks", typical of the Harz region. The Kästeklippen (Klippen = crags) are a popular destination in the Harz. From here, there are views to the Sudmerberg hill in the borough of Goslar. Numerous paths lead from the Oker Reservoir, Romkerhall, Oker, Göttingerode and Bad Harzburg up to the Käste. The most important access route is the Kästestraße. It runs from Bad Harzburg up to the Schlackenplatz on the Morlberg and then continues at a height of just under 600 m over the Alte Schlewecke and the crags of the Stiefmutterklippen to the Käste. From there it goes downhill again, past the Hinterer Ziegenrücken and Vorderen Ziegenrücken to Oker. The Kästestraße was once tarmacked all the way from Bad Harzburg to the Käste. Remnants of the asphalt surface can still be seen today. From the beginning of April to the end of October a bus service runs from Bad Harzburg to the Käste. The Kästehaus restaurant was demolished in 2019. The Kästehaus is checkpoint no. 118 in the Harzer Wandernadel hiking trail network.
