Dolmen D1 at Steenbergen is the westernmost and most geographically isolated of the Dutch hunebedden, situated away from the main concentration in the Drenthe province in what is now the province of Groningen. Its relative isolation from the main cluster of 53 surviving hunebedden is itself significant: the Funnel Beaker builders placed this monument at the edge of their known distribution, on glacial erratic boulders deposited by the Scandinavian ice sheet. The southern entrance orientation follows the island-wide convention documented across all Dutch hunebedden. Its isolation makes it a useful point for understanding the geographic extent of the Funnel Beaker megalithic tradition.
