D28 and D29 are twins, as
you can see. These small hunebeds lie close together and are of equal
size. D28, on the upper picture, has 3 capstones; one is missing. D29 originaly
had 3 capstones and here also one is missing. The 2 present however are
very large and very flat. Possibly they are the two parts of a very big boulder
that was split. But how..? Did the hunebed-builders have cleaving techniques
at their disposal...? There are some archaeologists in Holland who think
they did, for instance by alternately heating them by fire and cooling
them with water. But that's just a speculation. |
