Ahlhorner cellar stones

The Ahlhorner Kellersteine are two neolithic large stone graves located approximately 50 meters apart, classified as passage graves or large dolmens, with Sprockhoff numbers 939 and 940. They were created between 3500 and 2800 BC and are megalithic structures of the Funnel Beaker culture.
The passage grave is a construction form of Neolithic megalithic structures, consisting of a chamber and a laterally offset passage. This form is primarily found in Denmark, Germany, and Scandinavia, as well as occasionally in France and the Netherlands. Based on the ceramic findings, both structures are attributed to the older to middle phase of the Western group of the Funnel Beaker culture. "Neolithic monuments are expressions of the culture and ideology of Neolithic societies. Their creation and function are considered characteristics of social development."
