The Amelungsburg is a former ringfort that is located on the Amelungsberg hill on the Süntel ridge in the district of Hameln-Pyrmont in the German state of Lower Saxony.

There are the remains of a former entranceway on the southeastern side of the plateau just under 70 metres west of the present day breach in the defences by a forest track.

Below the site runs a rough 300 metre long advance rampart and moat which shows evidence of an entrance.

About 300 artefacts, including tools, iron wagon parts and tyres are assigned to the La Tène period.

Based on excavations, the fortifications were originally built in the pre-Roman Iron Age, archaeologists reckoning a construction time of up to six weeks.
