From the knapped flints that have been unearthed here, it can be concluded that the area around Oldendorf was settled as early as the Stone Age (8000 to 2000 BC).

Oldendorf was first mentioned in the records in a document dating to AD 968 by the Saxon duke, Hermann Billung.

On 10 August 1975 the largest forest fire in the Federal Republic of Germany broke out between Oldendorf and Eschede.

First, only gravel from the old fish ponds on Schlüpker Weg was extracted, but later the operation was continually expanded towards Eschede.

In 1986 a holiday home development of 32 small houses was established on the site of the first gravel pits to be exploited and subsequently abandoned.

In 1788 Field Marshal Johann Wilhelm von Reden[1] was given the fief of Hermannsburg-Oldendorf by George III, prince-elector of Hanover and King of England, for his service as a soldier.

When the son and heir Traugott Kothe fell in the First World War, his father sold Beutz Farm in 1917 for 440,000 marks to a judge, Wilhelm Meyer, from Hanover.

In 1933, Judge Meyer died and his wife sold the farm to Mr. Bertram, the Director of Hannover-Döhren Wool Washing, for 350,000 marks.

Chairman of the Beutz Farm board of trustees (Johanneshaus Beutzen) is Prof. Dr. Paul Imhoff, who is also director of the ASP.

The name comes from Peter Heinrich Dehning (1781–1832), a carter (Fuhrmann) from Oldendorf, who had been looking for a place to set up a staging inn at this spot as early as 1804.

After twice being rejected by the farmers from Oldendorf who had wood grazing rights there, he was granted a site, four morgens in area, on 11 May 1816, subject to various constraints.

Around 1950 its then owner, Gustav Stucke, built another restaurant, which he called Zur Alten Fuhrmannsschänke ("The Old Carter's Tavern") The property was not connected to mains electricity.

Next a power cable was laid to the Dehningshof and a hotel with a guest house for riders was established.
