Barigauer Turm, Observation tower in Oberhain, Germany

The Barigauer Turm is a 9-metre observation tower with a square base of 4.52 by 4.52 metres on the 665-metre Barigauer Höhe near Barigau, part of Königsee. A restaurant adjoins the tower, and a glazed domed top added in 1960 encloses the viewing level.

The Thüringerwald-Verein organization built and opened the tower in 1912 as a regional viewing point. This founding made the location an important stop for people exploring the landscape.

The tower's restaurant grew out of a small sales point run by Fritz Rusch from inside the tower in 1954, with the stairway used as storage. Villagers built the adjoining dining room in 1957–1959, contributing 2,644 voluntary work hours; it seated 35. Since 1976 the Freundeskreis Barigauer Turm has held the Turmfest on the hill.

The tower stands on the 665-metre Barigauer Höhe, the highest point of the former Rudolstadt district. Walking times given in 1912 were one hour from Königsee, two hours from Gehren and three-quarters of an hour from Mellenbach. The site is reached on foot; the tower itself is climbed via its stairway, which once served the first tower innkeeper as a storeroom.

The tower stands on the Barigauer Höhe, which the 1912 inauguration report gives as 665 metres high, not 666. The same report lists 43 places visible from the platform, among them the Leuchtenburg in Seitenroda, the Kulm near Saalfeld, the three Gleichen near Arnstadt and the Schneekopf.
