The Grebbeberg is a 52-meter high hill located east of Rhenen, Netherlands in the province of Utrecht.

Due to its strategic location with a view of the Lower Rhine and the Betuwe, this hill was historically of great importance.

The ring wall with dry moat, the so-called Heimenberg [nl], probably dates from the seventh century and has been restored several times.

In May 1940, Dutch soldiers fought a German assault army on the Grebbeberg, including Waffen-SS units.

A monument has been placed at the honorary cemetery where the dead from the Second World War are commemorated every year on May 4.

This allows the free-living herds of Konik horses and Galloway cattle to seek the safety of the mountain at high tide.

As a result of the erosive effect of the river system of the Rhine, the originally existing connection between the Utrechtse Heuvelrug and the moraine of Ede - Wageningen has been broken.
