Laute is a river of Lower Saxony, Germany. It is a right tributary of the Innerste. The Laute rises in the vicinity of Hahnenklee in the Upper Harz and discharges about 6 km (3.7 mi) later into the Innerste in Lautenthal. The source is at an elevation of about 540 m at the bottom of a mountain called Kuttelbacher Berg. The Laute flows to the west parallel to road L 516 which is called Hahnenkleer Straße in Lautenthal. The name of the town means Laute Valley. The mouth is at an elevation of about 300 m in the west of Wildemanner Strasse, the high street of Lautenthal. In 1875 a railway bridge of the Innerste Valley Railway was built over the Laute close to its mouth. Although the railway line was closed in 1977, the bridge is well preserved and still used by hikers. A flood of the Laute caused considerable damage in Lautenthal in 1877.

The Lutheran Gustav Adolf Stave Church (German: Gustav-Adolf-Stabkirche) is a stave church situated in Hahnenklee, a borough of Goslar in the Harz mountains, Germany. Construction of the church began in 1907 and it was consecrated on 28 June 1908. The church is a copy of the medieval Borgund Stave Church in Norway. It was erected during the sudden rise in Hahnenklee's popularity as a spa town and major tourist destination, with adaptions to fulfil its role as a parish church. The plans were designed by Karl Mohrmann (1857–1927), architect of the Evangelical-Lutheran Church of Hanover, a representative of the historicist Hanover school of architecture. He had visited Borgund and held the view that stave churches once were common in the medieval Saxon areas too. The church was built from spruce trunks harvested at the nearby Bocksberg mountain. The interior comprises numerous carvings of archaic symbols as well as Viking ship design features. The building soon became a frequently visited landmark and a popular wedding church.

The Upper Harz Water Regale (German: Oberharzer Wasserregal, pronounced [ˌoːbɐhaːɐ̯tsɐ ˈvasɐʁeɡaːl]) is a system of dams, reservoirs, ditches and other structures, much of which was built from the 16th to 19th centuries to divert and store the water that drove the water wheels of the mines in the Upper Harz region of Germany. The term regale, here, refers to the granting of royal privileges or rights (droit de régale) in this case to permit the use of water for mining operations in the Harz mountains of Germany. The Upper Harz Water Regale is one of the largest and most important historic mining water management systems in the world. The facilities developed for the generation of water power have been placed under protection since 1978 as cultural monuments. The majority are still used, albeit nowadays their purpose is primarily to support rural conservation (the preservation of a historic cultural landscape), nature conservation, tourism and swimming. From a water management perspective, several of the reservoirs still play a role in flood protection and the supply of drinking water. On 31 July 2010 the Regale was declared a UNESCO World Heritage Site affiliated with the Mines of Rammelsberg and the Historic Town of Goslar because of its importance in the development of mining techniques and testimony to the medieval history of ore mining.The water system covers an area of roughly 200 square kilometres (77 sq mi) within the Lower Saxon part of the Harz, the majority of structures being found in the vicinity of Clausthal-Zellerfeld, Hahnenklee, Sankt Andreasberg, Buntenbock, Wildemann, Lautenthal, Schulenberg, Altenau and Torfhaus.
