Eiche und Lügenstein, Natural monument in Göxe, Germany

Eiche und Lügenstein is a natural monument in Göxe consisting of a nearly circular sandstone slab about 1.5 m in diameter and 20 cm thick, resting on boulders at the foot of a large pedunculate oak. The oak, about 21 m tall with a trunk circumference of 4.66 m, stands at the junction of Bundesstraße 65 and Lügensteinweg next to a barn.

The natural monument "Oak with Devil's Stone" was listed in the district of Hannover's second ordinance on natural monuments of December 1937; the Region Hannover carried it over as ND-H 6 in 2010. The original coverstone, said to be the largest and heaviest boulder around, was rolled through the village and smashed by young men from neighbouring Stemmen in the 19th century, and its fragments were used for house building. The Stemmen men had to bring today's smaller sandstone slab to Göxe as a replacement.

The name refers to an old custom where anyone sitting on the sandstone was expected to speak only the truth. Today the site recalls village traditions of oaths and assembly, when stones served as fixed places for decisions or solemn promises.

The site lies directly at the junction of two roads and is easy to reach by car or on foot. The ground around the stone is firm, so visitors can view the spot comfortably even in wet weather.

The sandstone slab is not a millstone but a coverstone laid on boulders at the oak's foot. Legend says the Stemmen villagers rolled the original, larger slab through their village in the 19th century and broke it; the pieces went into house walls, and Stemmen had to deliver today's smaller slab to Göxe as a replacement.
