Osterode (district)

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).

Kleine Steinau is a river of Lower Saxony, Germany. It is a 9.1-kilometre-long (5.7 mi) tributary of the Sieber, north of Herzberg am Harz in the district of Göttingen. The Kleine Steina rises at about 690 m (2,260 ft) between the Schindelkopf mountain and the Spießerklippe crags on the ridge of Auf dem Acker. It initially flows in a westerly direction, but later swings south before emptying into the River Sieber near the small settlement of Aschenhütte, not far from the mouth of the Große Steinau. In the upper reaches of the Kleine Steinau it is also called the Schindelgraben, although it is not clear from the maps at which point the name changes.

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.

Lonau is a small village with a population of about 345 situated at an elevation of about 400m in the Harz Mountains of Northern Germany. Besides the clean air and lush forests, it is famous for the capercaillie. It belongs to the city of Herzberg am Harz which is about 4 km to the south. The rivers Große Lonau and Kleine Lonau join here.

The Große Schweimke is a river of Lower Saxony, Germany. It is 3.2 km (2.0 mi) long and a tributary of the Kleine Steinau, north of Herzberg am Harz in the district of Göttingen. It rises at about 602 m above sea level and 1 km (0.6 mi) south of the Schindelkopf and roughly 600 m (2,000 ft) north of the Weinbergstraße road on the ridge known as Auf dem Acker. It flows initially in a southwesterly direction before swinging west and discharging into the Kleine Steinau.

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.

Hörden am Harz is a municipality in the district of Göttingen, in Lower Saxony, Germany.

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.
