The Dutch name (literally 'Hun's grave') for a local variety of megalithic chamber tombs in the northern Netherlands and northern Germany. The tombs are built of large stones and consist of a round or oval mound surrounded by a kerb and covering a rectangular burial chamber with its entrance on one of the long sides. A few examples have an entrance passage, giving them a T plan which suggests an association with the passage graves of Denmark. The Danish tombs are slightly later than the oldest Dutch ones, but in both places they were built by the TRB culture during the Neolithic in the 4th and 3rd millennia BC.
