[2] The village is immediately west of the nature reserve that is located in the flood retention basin Salzderhelden.

Prehistoric settlements in the vicinity of the salt springs is proven: "From the Sülbecker mountain originate some tools that have been manufactured from Neanderthals resting there".

[3] During the development of a new housing area "Am Bohrturm" (At the Derrick) in the 1980s further archaeological investigations were carried out which showed that the settlements date back to about 5000 BC.

On 26 April 1686 the elector Ernst August of Hanover Calenberg ordere, that in Sülbeck, salt works, including a graduation tower were to be built.

The project was driven by Otto Friedrich von Moltke, the last resident of the castle Heldenburg, now ruined.

Therefore, the project was greatly expanded to include a graduation tower to increase the salinity of the brine to about 20%.

This first graduation tower was about 166 m long and stretched south from the current Sülbeck village square, Dorfplatz.

Thus a canal had to be dug to provide water supply from the river Leine, some kilometers upstream from Sülbeck.

At the edge of the current village square the canal made a 90° bend from south to east and the water flowed back into the river Leine about 1 km downstream.

A small timbered structure was erected over the first brinewell in 1668, which survived until the 1960s, and was taken away then to make room for a wider road intersection at Solstraße and Severshuser Weg.

By then it had access to the newly built railway line which connects Hannover with Kassel, about 3 km away.

In 1886 a small tug was obtained that towed the barges loaded with coal from Salzderhelden to Sülbeck.

During 1908 construction began for an aerial cableway to transport coal from the railway station of Salzderhelden to Sülbeck.

In 1899 a small hydroelectric power station with two turbines was installed in Sülbeck which used the water of the Salzgraben.

In some of the pictures, tracks of a narrow gauge field railway can be seen with a railroad switch on one end.

Since 1989 a local initiative from the south of Lower Saxony has organized a series of concerts known by name of "Kultur im Esel".

In 2013, artists including Chris Kavanagh, Sally Barker, and Vicki Genfan performed.
