Lonau

Kleine Lonau is a tributary of the Große Lonau in Lower Saxony, Germany. It rises at a height of 650 metres and flows through the Mariental valley to Lonau, where it merges with the Große Lonau. It is about 4.2 km (2.6 mi) long.

The Großer Mittelberg (the short form Mittelberg is also common) is a ridge in the Harz Mountains of Germany that begins immediately northeast of Lonau in the district of Göttingen in Lower Saxony. It separates the valley of Kirchtal, through which the Große Lonau flows, from the Mariental and the Kleine Lonau. is Although it is the nearest subpeak to the village of Lonau, the Großer Mittelberg is, at 531 metres, not the highest point, but may be viewed as a main summit due to its prominent location. From here on, the ridge only climbs gently in a northeasterly direction and has several more subpeaks with small wind gaps. To the north the Großer Mittelberg transitions to the ridge of Auf dem Acker without any noticeable wind gap. The Großer Mittelberg is almost entirely covered in beech woods and lies within the Harz National Park.

The Franzosenkopf is a 562 metre high hill in the Harz Mountains of central Germany, which lies about 1.4 kilometres northeast of Lonau in the district of Göttingen in Lower Saxony. To the north of the Franzosenkopf is the Braakberg, a shallow saddle separating them. Flowing around the Franzosenkopf to the east and south is the Kleine Lonau in the valley of Mariental ("Mary's Valley"). To the west the Franzosenkopf is separated from the Kargeskopf hill by the Hackenstieltal valley. The Franzosenkopf is mostly covered in beech, but spruce also occurs in places. It lies entirely within the Harz National Park.

The Braakberg is a 645.5 metre high mountain in the Harz in central Germany, in the unincorporated area of Harz in the district of Göttingen in the state of Lower Saxony.

The Langfast is a ridge in the district of Göttingen in North Germany. This ridge, with a height of 606 metres (1,988 ft), is located in the South Harz mountains between Herzberg am Harz and Sieber.

The Große Steinau is a river of Lower Saxony, Germany. It is a 7.8-kilometre-long (4.8 mi) tributary of the Sieber, north of Herzberg am Harz in the district of Göttingen. It rises at about 690 metres near the crags of the Sophienklippe on the Acker. It initially flows in a southwesterly direction, but later swings south before discharging into the Sieber near the small settlement of Aschenhütte, not far from the mouth of the Kleine Steinau. In times of drought the water of the Große Steinau seeps completely into the karst ground before its mouth and reappears about 4 days later at the Rhume Spring. An abandoned village, Steynowe, was probably located in the lower valley of the Große Steinau, but its exact location has not been found.

The Steile Wand (literally "steep wall", or "steep face") is a 518.9-metre-high (1,702 ft) hill ridge in the southwestern part of the Harz Mountains in the German state of Lower Saxony.

The Schindelkopf (629 m above sea level (NN)) in the Harz Mountains of central Germany is a southwestern outlier of the mountain ridge known as Auf dem Acker (865.1 m). It is located near the town of Osterode am Harz within the unincorporated area of Harz which is in the district of Göttingen in the state of Lower Saxony.

Osterode (German: [ˌɔstəˈʁoːdə] ) was a district in Lower Saxony, Germany. It was bounded by (from the southwest and clockwise) the districts of Göttingen, Northeim and Goslar, and by the state of Thuringia (districts of Nordhausen and Eichsfeld).

Herzberg Castle (German: Schloss Herzberg) is a German schloss in Herzberg am Harz in the district of Göttingen in the state of Lower Saxony. The present-day, quadrangular building has its origins in the 11th century as a medieval castle. After a fire in 1510 it was rebuilt as a schloss and is one of the few in Lower Saxony that was constructed as a timber-framed building. Because it belonged to the House of Welf for 700 years it is also known as the Welf Castle of Herzberg (Welfenschloss Herzberg).
